Function Documentation

PUBLIC void* Memory_calloc	(	size_t	num,
		size_t	size
	)

Allocates an array in memory with elements initialized to 0.

Parameters:

[in]	num	Number of elements.
[in]	size	Bytes to allocate.

Returns:

Void pointer to the allocated space on success, or NULL if there is insufficient memory available.

PUBLIC void Memory_free

(

void *

memblock

)

Deallocates or frees a memory block.

Parameters:

[in]

memblock

Previously allocated memory block to be freed.

Returns:

Nothing.

PUBLIC void* Memory_malloc

(

size_t

size

)

Allocates memory blocks.

Parameters:

[in]

size

Bytes to allocate.

Returns:

Void pointer to the allocated space on success, or NULL if there is insufficient memory available.

PUBLIC void Memory_outofmem	(	const char *	name,
		const char *	file,
		W32	line
	)

Print message out of memory.

Parameters:

[in]	name	Name of function this occurred in.
[in]	file	File name that this occurred in.
[in]	line	Line number this occurred on.

Returns:

Nothing.

PUBLIC void* Memory_realloc	(	void *	memblock,
		size_t	size
	)

Reallocate memory blocks.

Parameters:

[in]	memblock	Pointer to previously allocated memory block.
[in]	size	Bytes to allocate.

Returns:

A void pointer to the reallocated (and possibly moved) memory block. The return value is NULL if the size is zero and the buffer argument is not NULL, or if there is not enough available memory to expand the block to the given size.
