Function Documentation

sgl_memcpy()

void * sgl_memcpy	(	void *	destination,
		const void *	source,
		sgl_size_t	size
	)

Copies bytes between non-overlapping memory ranges.

Parameters

[out]	destination	Writable range containing at least size bytes.
[in]	source	Readable range containing at least size bytes.
[in]	size	Number of bytes to copy.

Returns

destination.

Precondition

The two ranges do not overlap. Use with a zero size is valid.

sgl_memset()

void * sgl_memset	(	void *	destination,
		sgl_int32_t	value,
		sgl_size_t	size
	)

Fills a memory range with one byte value.

Parameters

[out]	destination	Writable range containing at least size bytes.
[in]	value	Value whose low eight bits are stored in each byte.
[in]	size	Number of bytes to set.

Returns

destination.
