43 @brief Implementation of a byte input-output process (CIO)
45 The functions in CIO.C have for goal to realize a byte input / output process.
48 /** @defgroup CIO CIO - byte input-output stream */
51 /** @name Exported functions (see also openjpeg.h) */
53 /* ----------------------------------------------------------------------- */
55 Number of bytes left before the end of the stream
57 @return Returns the number of bytes before the end of the stream
59 int cio_numbytesleft(opj_cio_t *cio);
61 Get pointer to the current position in the stream
63 @return Returns a pointer to the current position
65 unsigned char *cio_getbp(opj_cio_t *cio);
69 @param v Value to write
70 @param n Number of bytes to write
71 @return Returns the number of bytes written or 0 if an error occured
73 unsigned int cio_write(opj_cio_t *cio, unsigned int64 v, int n);
77 @param n Number of bytes to read
78 @return Returns the value of the n bytes read
80 unsigned int cio_read(opj_cio_t *cio, int n);
84 @param n Number of bytes to skip
86 void cio_skip(opj_cio_t *cio, int n);
