Function Documentation

memmove32_s()

errno_t memmove32_s	(	uint32_t *	dest,
		rsize_t	dmax,
		const uint32_t *	src,
		rsize_t	smax
	)

The memmove32_s function copies smax uint32_ts from the region pointed to by src into the region pointed to by dest.

This copying takes place as if the smax uint32_ts from the region pointed to by src are first copied into a temporary array of smax uint32_ts that does not overlap the regions pointed to by dest or src, and then the smax uint32_ts from the temporary array are copied into the region pointed to by 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 the memory that will be replaced by src.
[in]	dmax	maximum length of the resulting dest, in bytes
[in]	src	pointer to the memory that will be copied to dest
[in]	smax	maximum number bytes of src that can be copied

Precondition

Neither dest nor src shall be a null pointer.

Neither dmax nor smax shall be 0.

dmax shall not be greater than RSIZE_MAX_MEM.

smax shall not be greater than dmax.

Returns

If there is a runtime-constraint violation, the memmove_s function stores zeros in the first dmax characters of the region pointed to by dest if dest is not a null pointer and dmax is not greater than RSIZE_MAX_MEM.

Return values

EOK	when operation is successful
ESNULLP	when dst/src is NULL POINTER
ESZEROL	when dmax/smax = ZERO
ESLEMAX	when dmax/smax > RSIZE_MAX_MEM
ESNOSPC	when dmax < smax
