32 @brief Internal functions
34 The functions in J2K_LIB.C are internal utilities mainly used for memory management.
37 /** @defgroup MISC MISC - Miscellaneous internal functions */
40 /** @name Exported functions */
42 /* ----------------------------------------------------------------------- */
45 Difference in successive opj_clock() calls tells you the elapsed time
46 @return Returns time in seconds
51 Allocate a memory block with elements initialized to 0
52 @param size Bytes to allocate
53 @return Returns a void pointer to the allocated space, or NULL if there is insufficient memory available
55 void* opj_malloc( size_t size );
58 Reallocate memory blocks.
59 @param memblock Pointer to previously allocated memory block
60 @param size New size in bytes
61 @return Returns a void pointer to the reallocated (and possibly moved) memory block
63 void* j2k_realloc( void *memblock, size_t size );
66 Deallocates or frees a memory block.
67 @param memblock Previously allocated memory block to be freed
69 void opj_free( void *memblock );
