Here is the call graph for this function:

ghost_error ghost_malloc	(	void **	mem,
		const size_t	size
	)

Allocate memory.

Parameters

mem	Where to store the allocated memory.
size	The size (in bytes) to allocate.

Returns

GHOST_SUCCESS on success or an error indicator.

ghost_error ghost_malloc_align	(	void **	mem,
		const size_t	size,
		const size_t	align
	)

Allocate aligned memory.

Parameters

mem	Where to store the allocated memory.
size	The size (in bytes) to allocate.
align	The alignment size.

Returns

GHOST_SUCCESS on success or an error indicator.

ghost_error ghost_malloc_pinned	(	void **	mem,
		const size_t	size
	)

Allocate pinned memory to enable fast CPU-GPU transfers.

Parameters

mem	Where to store the allocated memory.
size	The size (in bytes) to allocate.

Returns

GHOST_SUCCESS on success or an error indicator.

If CUDA is not enabled, a normal malloc is done.
