#define HAVE_MEMALIGN

Allocate memory aligned to a 16 byte boundry.

Parameters

size	Bytes to allocate

Returns

Returns a void pointer to the allocated space, or NULL if there is insufficient memory available

)

memalign(16, (size))

opj_calloc

#define opj_calloc	(		num,
			size
	)		calloc(num, size)

Allocate a memory block with elements initialized to 0.

Parameters

num	Blocks to allocate
size	Bytes per block to allocate

Returns

Returns a void pointer to the allocated space, or NULL if there is insufficient memory available

opj_free

#define opj_free

(

m

)

free(m)

Deallocates or frees a memory block.

Parameters

m	Previously allocated memory block to be freed

(

size

)

malloc(size)

Allocate an uninitialized memory block.

Parameters

size	Bytes to allocate

Returns

Returns a void pointer to the allocated space, or NULL if there is insufficient memory available

opj_realloc

#define opj_realloc	(		m,
			s
	)		realloc(m, s)

Reallocate memory blocks.

Parameters

m	Pointer to previously allocated memory block
s	New size in bytes

Returns

Returns a void pointer to the reallocated (and possibly moved) memory block
