- Communication," Dr. Dobbs Portal, http://www.ddj.com/,
- articleID=189401457, June 15, 2006. This algorithm requires
- that messages be translated to a form where no words contain
- zeros. Each word becomes its own "data valid" tag. Because of
- this translation, we cannot return a pointer to data still in
- the queue when the "peek" method is called. Instead, a buffer
- is preallocated so that data can be copied there. Pm_QueuePeek()
- dequeues a message into this buffer and returns a pointer to
- it. A subsequent Pm_Dequeue() will copy from this buffer.
-
- This implementation does not try to keep reader/writer data in
- separate cache lines or prevent thrashing on cache lines.
- However, this algorithm differs by doing inserts/removals in
- units of messages rather than units of machine words. Some
- performance improvement might be obtained by not clearing data
- immediately after a read, but instead by waiting for the end
- of the cache line, especially if messages are smaller than
- cache lines. See the Dokumentov article for explanation.
-
- The algorithm is extended to handle "overflow" reporting. To report
- an overflow, the sender writes the current tail position to a field.
- The receiver must acknowlege receipt by zeroing the field. The sender
- will not send more until the field is zeroed.

-/* CHANGELOG FOR PORTMIDI
- * (see ../CHANGELOG.txt)
- *
- * NOTES ON HOST ERROR REPORTING:
- *
- * PortMidi errors (of type PmError) are generic, system-independent errors.
- * When an error does not map to one of the more specific PmErrors, the
- * catch-all code pmHostError is returned. This means that PortMidi has
- * retained a more specific system-dependent error code. The caller can
- * get more information by calling Pm_HasHostError() to test if there is
- * a pending host error, and Pm_GetHostErrorText() to get a text string
- * describing the error. Host errors are reported on a per-device basis
- * because only after you open a device does PortMidi have a place to
- * record the host error code. I.e. only
- * those routines that receive a (PortMidiStream *) argument check and
- * report errors. One exception to this is that Pm_OpenInput() and
- * Pm_OpenOutput() can report errors even though when an error occurs,
- * there is no PortMidiStream* to hold the error. Fortunately, both
- * of these functions return any error immediately, so we do not really
- * need per-device error memory. Instead, any host error code is stored
- * in a global, pmHostError is returned, and the user can call
- * Pm_GetHostErrorText() to get the error message (and the invalid stream
- * parameter will be ignored.) The functions
- * pm_init and pm_term do not fail or raise
- * errors. The job of pm_init is to locate all available devices so that
- * the caller can get information via PmDeviceInfo(). If an error occurs,
- * the device is simply not listed as available.
- *
- * Host errors come in two flavors:
- * a) host error
- * b) host error during callback
- * These can occur w/midi input or output devices. (b) can only happen
- * asynchronously (during callback routines), whereas (a) only occurs while
- * synchronously running PortMidi and any resulting system dependent calls.
- * Both (a) and (b) are reported by the next read or write call. You can
- * also query for asynchronous errors (b) at any time by calling
- * Pm_HasHostError().
- *
- * NOTES ON COMPILE-TIME SWITCHES
- *
- * DEBUG assumes stdio and a console. Use this if you want automatic, simple
- * error reporting, e.g. for prototyping. If you are using MFC or some
- * other graphical interface with no console, DEBUG probably should be
- * undefined.
- * PM_CHECK_ERRORS more-or-less takes over error checking for return values,
- * stopping your program and printing error messages when an error
- * occurs. This also uses stdio for console text I/O.

- named pmdefaults that is part of the PortMidi distribution. This

- java.util.prefs.Preferences.userRoot().node("/PortMidi"); the

- devices and name is the name of the device. These correspond to

- interfaces are "MMSystem" for Win32, "ALSA" for Linux, and
- "CoreMIDI" for OS X, so in fact, there is no choice of interface.)
- In "interf, name", the strings are actually substrings of
- the full interface and name strings. For example, the preference
- "Core, Sport" will match a device with interface "CoreMIDI"
- and name "In USB MidiSport 1x1". It will also match "CoreMIDI"
- and "In USB MidiSport 2x2". The devices are enumerated in device
- ID order, so the lowest device ID that matches the pattern becomes
- the default device. Finally, if the comma-space (", ") separator
- between interface and name parts of the preference is not found,
- the entire preference string is interpreted as a name, and the
- interface part is the empty string, which matches anything.
-
- On the MAC, preferences are stored in
- /Users/$NAME/Library/Preferences/com.apple.java.util.prefs.plist
- which is a binary file. In addition to the pmdefaults program,
- there are utilities that can read and edit this preference file.

-
- inputDevice is the id of the device used for input (see PmDeviceID above).
-
- inputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or handle processing.
- inputDriverInfo is never required for correct operation. If not used
- inputDriverInfo should be NULL.
-
- outputDevice is the id of the device used for output (see PmDeviceID above.)
-
- outputDriverInfo is a pointer to an optional driver specific data structure
- containing additional information for device setup or handle processing.
- outputDriverInfo is never required for correct operation. If not used
- outputDriverInfo should be NULL.
-
- For input, the buffersize specifies the number of input events to be
- buffered waiting to be read using Pm_Read(). For output, buffersize
- specifies the number of output events to be buffered waiting for output.
- (In some cases -- see below -- PortMidi does not buffer output at all
- and merely passes data to a lower-level API, in which case buffersize
- is ignored.)
-
- latency is the delay in milliseconds applied to timestamps to determine
- when the output should actually occur. (If latency is < 0, 0 is assumed.)
- If latency is zero, timestamps are ignored and all output is delivered
- immediately. If latency is greater than zero, output is delayed until the
- message timestamp plus the latency. (NOTE: the time is measured relative
- to the time source indicated by time_proc. Timestamps are absolute,
- not relative delays or offsets.) In some cases, PortMidi can obtain
- better timing than your application by passing timestamps along to the
- device driver or hardware. Latency may also help you to synchronize midi
- data to audio data by matching midi latency to the audio buffer latency.
-
- time_proc is a pointer to a procedure that returns time in milliseconds. It
- may be NULL, in which case a default millisecond timebase (PortTime) is
- used. If the application wants to use PortTime, it should start the timer
- (call Pt_Start) before calling Pm_OpenInput or Pm_OpenOutput. If the
- application tries to start the timer *after* Pm_OpenInput or Pm_OpenOutput,
- it may get a ptAlreadyStarted error from Pt_Start, and the application's
- preferred time resolution and callback function will be ignored.
- time_proc result values are appended to incoming MIDI data, and time_proc
- times are used to schedule outgoing MIDI data (when latency is non-zero).
-
- time_info is a pointer passed to time_proc.
-
- Example: If I provide a timestamp of 5000, latency is 1, and time_proc
- returns 4990, then the desired output time will be when time_proc returns
- timestamp+latency = 5001. This will be 5001-4990 = 11ms from now.

- PmEvent carries the status byte.
-
- Note that MIDI allows nested messages: the so-called "real-time" MIDI
- messages can be inserted into the MIDI byte stream at any location,
- including within a sysex message. MIDI real-time messages are one-byte
- messages used mainly for timing (see the MIDI spec). PortMidi retains
- the order of non-real-time MIDI messages on both input and output, but
- it does not specify exactly how real-time messages are processed. This
- is particulary problematic for MIDI input, because the input parser
- must either prepare to buffer an unlimited number of sysex message
- bytes or to buffer an unlimited number of real-time messages that
- arrive embedded in a long sysex message. To simplify things, the input
- parser is allowed to pass real-time MIDI messages embedded within a
- sysex message, and it is up to the client to detect, process, and
- remove these messages as they arrive.
-
- When receiving sysex messages, the sysex message is terminated
- by either an EOX status byte (anywhere in the 4 byte messages) or
- by a non-real-time status byte in the low order byte of the message.
- If you get a non-real-time status byte but there was no EOX byte, it
- means the sysex message was somehow truncated. This is not
- considered an error; e.g., a missing EOX can result from the user
- disconnecting a MIDI cable during sysex transmission.
-
- A real-time message can occur within a sysex message. A real-time
- message will always occupy a full PmEvent with the status byte in
- the low-order byte of the PmEvent message field. (This implies that
- the byte-order of sysex bytes and real-time message bytes may not
- be preserved -- for example, if a real-time message arrives after
- 3 bytes of a sysex message, the real-time message will be delivered
- first. The first word of the sysex message will be delivered only
- after the 4th byte arrives, filling the 4-byte PmEvent message field.
-
- The timestamp field is observed when the output port is opened with
- a non-zero latency. A timestamp of zero means "use the current time",
- which in turn means to deliver the message with a delay of
- latency (the latency parameter used when opening the output port.)
- Do not expect PortMidi to sort data according to timestamps --
- messages should be sent in the correct order, and timestamps MUST
- be non-decreasing. See also "Example" for Pm_OpenOutput() above.
-
- A sysex message will generally fill many PmEvent structures. On
- output to a PortMidiStream with non-zero latency, the first timestamp
- on sysex message data will determine the time to begin sending the
- message. PortMidi implementations may ignore timestamps for the
- remainder of the sysex message.
-
- On input, the timestamp ideally denotes the arrival time of the
- status byte of the message. The first timestamp on sysex message
- data will be valid. Subsequent timestamps may denote
- when message bytes were actually received, or they may be simply
- copies of the first timestamp.
-
- Timestamps for nested messages: If a real-time message arrives in
- the middle of some other message, it is enqueued immediately with
- the timestamp corresponding to its arrival time. The interrupted
- non-real-time message or 4-byte packet of sysex data will be enqueued
- later. The timestamp of interrupted data will be equal to that of
- the interrupting real-time message to insure that timestamps are
- non-decreasing.

- Pm_Read() retrieves midi data into a buffer, and returns the number

- Buffer Overflow
-
- The problem: if an input overflow occurs, data will be lost, ultimately
- because there is no flow control all the way back to the data source.
- When data is lost, the receiver should be notified and some sort of
- graceful recovery should take place, e.g. you shouldn't resume receiving
- in the middle of a long sysex message.
-
- With a lock-free fifo, which is pretty much what we're stuck with to
- enable portability to the Mac, it's tricky for the producer and consumer
- to synchronously reset the buffer and resume normal operation.
-
- Solution: the buffer managed by PortMidi will be flushed when an overflow
- occurs. The consumer (Pm_Read()) gets an error message (pmBufferOverflow)
- and ordinary processing resumes as soon as a new message arrives. The
- remainder of a partial sysex message is not considered to be a "new
- message" and will be flushed as well.

-README_MAC.txt for PortMidi
-Roger Dannenberg
-20 nov 2009
-revised 20 Sep 2010 for Xcode 3.2.4 and CMake 8.2-2
-
-To build PortMidi for Mac OS X, you must install Xcode and
-CMake.
-
-CMake can build either command-line Makefiles or Xcode projects.
-These approaches are described in separate sections below.
-
-==== CLEANING UP ====
-(Skip this for now, but later you might want start from a clean
-slate.)
-
-Start in the portmedia/portmidi directory.
-
-make -f pm_mac/Makefile.osx clean
-
-will remove .o, CMakeFiles, and other intermediate files.
-
-Using "cleaner" instead of "clean" will also remove jni-related
-intermediate files.
-
-Using "cleanest" instead of "clean" or "cleaner" will also remove
-application binaries and the portmidi libraries. (It will not
-uninstall anything, however.)
-
-==== USING CMAKE (AND COMMAND LINE TOOLS) ====
-
-Start in the portmedia/portmidi directory.
-
-make -f pm_mac/Makefile.osx
-
-(Begin note: make will invoke cmake to build a Makefile and then make to
-build portmidi. This extra level allows you to correctly build
-both Release and Debug versions. Release is the default, so to get
-the Debug version, use:
-
-make -f pm_mac/Makefile.osx configuration=Debug
-)
-
-Release version executables and libraries are now in
- portmedia/portmidi/Release
-
-Debug version executables and libraries are created in
- portmedia/portmidi/Debug
-The Debug versions are compiled with PM_CHECK_ERRORS which
-prints an error message and aborts when an error code is returned
-by PortMidi functions. This is useful for small command line
-applications. Otherwise, you should check and handle error returns
-in your program.
-
-You can install portmidi as follows:
-
-cd Release; sudo make install
-
-This will install /usr/local/include/{portmidi.h, porttime.h}
-and /usr/local/lib/{libportmidi.dylib, libportmidi_s.a, libpmjni.dylib}
-
-You should now make the pmdefaults.app:
-
-make -f pm_mac/Makefile.osx pmdefaults
-
-NOTE: pmdefaults.app will be in pm_mac/Release/.
-
-Please copy pmdefaults.app to your Applications folder or wherever
-you would normally expect to find it.
-
-==== USING CMAKE TO BUILD Xcode PROJECT ====
-
-Before you can use Xcode, you need a portmidi.xcodeproj file.
-CMake builds a location-dependent Xcode project, so unfortunately
-it is not easy to provide an Xcode project that is ready to use.
-Therefore, you should make your own. Once you have it, you can
-use it almost like any other Xcode project, and you will not have
-to go back to CMake.
-
-(1) Install CMake if you do not have it already.
-
-(2) Open portmedia/portmidi/CMakeLists.txt with CMake
-
-(3) Use Configure and Generate buttons
-
-(4) This creates portmedia/portmidi/portmidi.xcodeproj.
-
-Note: You will also use pm_mac/pm_mac.xcodeproj, which
-is not generated by CMake.
-
-(5) Open portmidi/portmidi.xcodeproj with Xcode and
-build what you need. The simplest thing is to build the
-ALL_BUILD target. The default will be to build the Debug
-version, but you may want to change this to Release.
-
-NOTE: ALL_BUILD may report errors. Try simply building again
-or rebuilding specific targets that fail until they build
-without errors. There appears to be a race condition or
-missing dependencies in the build system.
-
-The Debug version is compiled with PM_CHECK_ERRORS, and the
-Release version is not. PM_CHECK_ERRORS will print an error
-message and exit your program if any error is returned from
-a call into PortMidi.
-
-CMake (currently) also creates MinSizRel and RelWithDebInfo
-versions, but only because I cannot figure out how to disable
-them.
-
-You will probably want the application PmDefaults, which sets
-default MIDI In and Out devices for PortMidi. You may also
-want to build a Java application using PortMidi. Since I have
-not figured out how to use CMake to make an OS X Java application,
-use pm_mac/pm_mac.xcodeproj as follows:
-
-(6) open pm_mac/pm_mac.xcodeproj
-
-(7) pm_java/pmjni/portmidi_JportmidiApi.h is needed
-by libpmjni.jnilib, the Java native interface library. Since
-portmidi_JportmidiApi.h is included with PortMidi, you can skip
-to step 8, but if you really want to rebuild everything from
-scratch, build the JPortMidiHeaders project first, and continue
-with step 8:
-
-(8) If you did not build libpmjni.dylib using portmidi.xcodeproj,
-do it now. (It depends on portmidi_JportmidiApi.h, and the
-PmDefaults project depends on libpmjni.dylib.)
-
-(9) Returning to pm_mac.xcodeproj, build the PmDefaults program.
-
-(10) If you wish, copy pm_mac/build/Deployment/PmDefaults.app to
-your applications folder.
-
-(11) If you want to install libportmidi.dylib, first make it with
-Xcode, then
- sudo make -f pm_mac/Makefile.osx install
-This command will install /usr/local/include/{porttime.h, portmidi.h}
-and /usr/local/lib/libportmidi.dylib
-Note that the "install" function of xcode creates portmidi/Release
-and does not install the library to /usr/local/lib, so please use
-the command line installer.

- since the input and output streams are represented by MIDIEndpointRef
- values and almost no other state, we store the MIDIEndpointRef on
- descriptors[midi->device_id].descriptor. The only other state we need
- is for errors: we need to know if there is an error and if so, what is
- the error text. We use a structure with two kinds of
- host error: "error" and "callback_error". That way, asynchronous callbacks
- do not interfere with other error information.
-
- OS X does not seem to have an error-code-to-text function, so we will
- just use text messages instead of error codes.

-readbinaryplist.c -- Roger B. Dannenberg, Jun 2008
-Based on ReadBinaryPList.m by Jens Ayton, 2007
-
-Note that this code is intended to read preference files and has an upper
-bound on file size (currently 100MB) and assumes in some places that 32 bit
-offsets are sufficient.
-
-Here are his comments:
-
-Reader for binary property list files (version 00).
-
-This has been found to work on all 566 binary plists in my ~/Library/Preferences/
-and /Library/Preferences/ directories. This probably does not provide full
-test coverage. It has also been found to provide different data to Apple's
-implementation when presented with a key-value archive. This is because Apple's
-implementation produces undocumented CFKeyArchiverUID objects. My implementation
-produces dictionaries instead, matching the in-file representation used in XML
-and OpenStep plists. See extract_uid().
-
-Full disclosure: in implementing this software, I read one comment and one
-struct defintion in CFLite, Apple's implementation, which is under the APSL
-license. I also deduced the information about CFKeyArchiverUID from that code.
-However, none of the implementation was copied.

-/* A note about memory management:
-Strings and possibly other values are unique and because the values
-associated with IDs are cached, you end up with a directed graph rather
-than a tree. It is tricky to free the data because if you do a simple
-depth-first search to free nodes, you will free nodes twice. I decided
-to allocate memory from blocks of 1024 bytes and keep the blocks in a
-list associated with but private to this module. So the user should
-access this module by calling:
- bplist_read_file() or bplist_read_user_pref() or
- bplist_read_system_pref()
-which returns a value. When you are done with the value, call
- bplist_free_data()
-This will of course free the value_ptr returned by bplist_read_*()
-
-To deal with memory exhaustion (what happens when malloc returns
-NULL?), use setjmp/longjmp -- a single setjmp protects the whole
-parser, and allocate uses longjmp to abort. After abort, memory
-is freed and NULL is returned to caller. There is not much here
-in the way of error reporting.
-
-Memory is obtained by calling allocate which either returns the
-memory requested or calls longjmp, so callers don't have to check.

-A note about buffers: WinMM seems to hold onto buffers longer than

-long sysex messages, at some point WinMM held both buffers. This problem
-was fixed by making buffers bigger. Therefore, it seems that there should
-be enough buffer space to hold a whole sysex message.
-
-The bufferSize passed into Pm_OpenInput (passed into here as buffer_len)
-will be used to estimate the largest sysex message (= buffer_len * 4 bytes).
-Call that the max_sysex_len = buffer_len * 4.
-
-For simple midi output (latency == 0), allocate 3 buffers, each with half
-the size of max_sysex_len, but each at least 256 bytes.
-
-For stream output, there will already be enough space in very short
-buffers, so use them, but make sure there are at least 16.
-
-For input, use many small buffers rather than 2 large ones so that when
-there are short sysex messages arriving frequently (as in control surfaces)
-there will be more free buffers to fill. Use max_sysex_len / 64 buffers,
-but at least 16, of size 64 bytes each.

-// SCOPED_ENUM is a macro that defines an enum inside a class with a given name, thus declaring the enum values
-// inside a named scope. This allows declaring:
-// SCOPED_ENUM(SomeType)
-// {
-// Val1,
-// Val2,
-// Val3
-// }
-// SCOPED_ENUM_END
-// And then you can reference SomeType::Val1, SomeType::Val2, SomeType::Val3 for the various values, unlike
-// a regular enum on which Val1, Val2 and Val3 would become global names.
-// Additionally, you get SomeType::Type to specify the type of the whole enum in case you want to transfer it to
-// a function.
-// Don't forget to close the enum with SCOPED_ENUM_END, otherwise you'll get bogus compilation errors.
-// This requirement can probably be removed some day, but it will make the SCOPED_ENUM macro much less readable...
