Function Documentation

memset16_s()

errno_t memset16_s	(	uint16_t *	dest,
		rsize_t	smax,
		uint16_t	value,
		rsize_t	n
	)

Sets the first n uint16_t values starting at dest to the specified value, but maximal smax 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]	smax	maximum number of bytes to be written
[in]	value	byte value to be written
[in]	n	number of bytes to be set

Precondition

dest shall not be a null pointer.

smax and n shall not be 0 nor greater than RSIZE_MAX_MEM.

n shall not be 0 nor greater than RSIZE_MAX_MEM16.

smax*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 smax is not larger than RSIZE_MAX_MEM, then, before reporting the runtime-constraints violation, memset16_s() copies smax bytes to the destination.

Return values

EOK	when operation is successful
ESNULLP	when dest is NULL POINTER
ESZEROL	when n = ZERO
ESLEMAX	when smax or n > RSIZE_MAX_MEM
ESNOSPC	when smax/2 < n
