49 @brief Implementation of a byte input-output process (CIO)
51 The functions in CIO.C have for goal to realize a byte input / output process.
54 /** @defgroup CIO CIO - byte input-output stream */
57 /** @name Exported functions (see also openjpeg.h) */
59 /* ----------------------------------------------------------------------- */
61 Number of bytes left before the end of the stream
63 @return Returns the number of bytes before the end of the stream
65 int cio_numbytesleft(opj_cio_t *cio);
67 Get pointer to the current position in the stream
69 @return Returns a pointer to the current position
71 unsigned char *cio_getbp(opj_cio_t *cio);
75 @param v Value to write
76 @param n Number of bytes to write
77 @return Returns the number of bytes written or 0 if an error occurred
79 OPJ_API unsigned int OPJ_CALLCONV cio_write(opj_cio_t *cio, unsigned int64 v, int n);
83 @param n Number of bytes to read
84 @return Returns the value of the n bytes read
86 OPJ_API unsigned int OPJ_CALLCONV cio_read(opj_cio_t *cio, int n);
90 @param n Number of bytes to skip
92 OPJ_API void OPJ_CALLCONV cio_skip(opj_cio_t *cio, int n);
