Function Documentation

memzero32_s()

EXPORT errno_t memzero32_s	(	uint32_t *	dest,
		rsize_t	len
	)

Zeros len uint32_ts starting at dest.

Remarks

EXTENSION TO ISO/IEC JTC1 SC22 WG14 N1172, Programming languages, environments and system software interfaces, Extensions to the C Library, Part I: Bounds-checking interfaces

Parameters

[out]	dest	pointer to memory to be zeroed.
[in]	len	number of uint32_ts to be zeroed

Precondition

dest shall not be a null pointer.

len shall not be 0 nor greater than RSIZE_MAX_MEM32.

Returns

If there is a runtime constraint, the operation is not performed.

Return values

EOK	when operation is successful
ESNULLP	when dest is NULL POINTER
ESZEROL	when len = ZERO
ESLEMAX	when len > RSIZE_MAX_MEM32
