memset16_s()

EXPORT errno_t memset16_s	(	uint16_t *	dest,
		rsize_t	dmax,
		uint16_t	value,
		rsize_t	n
	)

Sets the first n uint16_t values starting at dest to the specified value, but maximal dmax bytes.

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 that will be set to the value
[in]	dmax	maximum number of bytes to be written
[in]	value	byte value to be written
[in]	n	number of short (2-byte) words to be set

Precondition

dest shall not be a null pointer.

dmax shall not be 0

dmax shall not be greater than RSIZE_MAX_MEM.

n shall not be greater than RSIZE_MAX_MEM16.

dmax*2 may not be smaller than n.

Returns

If there is a runtime-constraints violation, and if dest is not a null pointer, and if dmax is not larger than RSIZE_MAX_MEM, then, before reporting the runtime-constraints violation, memset16_s() copies dmax bytes to the destination.

Return values

EOK	when operation is successful
ESNULLP	when dest is NULL POINTER
ESZEROL	Only before C11 when n = ZERO
ESLEMAX	when dmax > RSIZE_MAX_MEM
ESLEMAX	when n > RSIZE_MAX_MEM16
ESNOSPC	when dmax/2 < n
