Detailed Description

Functions used for modifying and allocating memory.

Similar to the memory functions provided by the C standard library.

Variable Documentation

void(* Mem_Free) (void *ptr) ( void * ptr )

extern

Frees memory allocated by malloc, allowing it to be reused.

Parameters

ptr	The pointer to the allocated region of memory to free.

void ( Mem_Memcpy) (void destination, const void source, size_t num) __attribute__((access(read_only	(	void *	destination,
		const void *	source,
		size_t	num
	)

extern

Copies one region of memory to another. Equivalent to the C standard library function with the same name.

Copies num bytes from source to destination.

Parameters

[out]	destination	A pointer to the destination of the copy.
[in]	source	A pointer to the source for the copy.
	num	The number of bytes to copy.

void ( Mem_Memset) (void *ptr, int value, size_t num) __attribute__((access(write_only	(	void *	ptr,
		int	value,
		size_t	num
	)

extern

Sets a region of memory to a specific value. Equivalent to the C standard library function with the same name.

Fills the region pointed to by ptr with num bytes of value value (zero-extended to a byte).

Parameters

[out]	ptr	A pointer to the region of memory to fill.
	value	The value to fill the memory region with.
	num	The number of bytes to fill.
