40 @brief Implementation of a byte input-output process (CIO)
42 The functions in CIO.C have for goal to realize a byte input / output process.
45 /** @defgroup CIO CIO - byte input-output stream */
48 /** @name Funciones generales (see also openjp3d.h) */
50 /* ----------------------------------------------------------------------- */
52 Number of bytes left before the end of the stream
54 @return Returns the number of bytes before the end of the stream
56 int cio_numbytesleft(opj_cio_t *cio);
58 Get pointer to the current position in the stream
60 @return Returns a pointer to the current position
62 unsigned char *cio_getbp(opj_cio_t *cio);
66 @param v Value to write
67 @param n Number of bytes to write
68 @return Returns the number of bytes written or 0 if an error occured
70 unsigned int cio_write(opj_cio_t *cio, unsigned int v, int n);
74 @param n Number of bytes to read
75 @return Returns the value of the n bytes read
77 unsigned int cio_read(opj_cio_t *cio, int n);
81 @param n Number of bytes to skip
83 void cio_skip(opj_cio_t *cio, int n);
87 @param v Signed integer value to write
88 @param n Number of bytes to write
89 @return Returns the number of bytes written or 0 if an error occured
91 int cio_write_int(opj_cio_t *cio, int v, int n);
95 @param n Number of bytes to read
96 @return Returns the value of the n bytes read
98 int cio_read_int(opj_cio_t *cio, int n);
