Function Documentation

static void* m4ri_mmc_calloc	(	size_t	count,
		size_t	size
	)		[inline, static]

Allocate an array of count times size zeroed bytes.

Parameters:

count	Number of elements.
size	Number of bytes per element.

Returns:

Pointer to allocated memory block.

void m4ri_mmc_cleanup

(

void

)

Cleans up memory block cache.

This function is called automatically when the shared library is unloaded.

Warning:

Not thread safe.

void m4ri_mmc_free	(	void *	condemned,
		size_t	size
	)

Free the data pointed to by condemned of the given size.

Parameters:

condemned	Pointer to memory.
size	Number of bytes.

Warning:

Not thread safe.

void* m4ri_mmc_malloc

(

size_t

size

)

Allocate size bytes.

Parameters:

size	Number of bytes.

Returns:

pointer to allocated memory block.
