◆ strcpyfldin_s()

EXPORT errno_t strcpyfldin_s	(	char *	dest,
		rsize_t	dmax,
		const char *	src,
		rsize_t	slen
	)

The strcpyfldin_s function copies at most slen characters from the null terminated string pointed to by src into the fixed character array pointed to by dest.

The copy operation stops on the null character if encountered and then continues to fill the field with nulls up to dmax characters.

Remarks: EXTENSION TO ISO/IEC TR 24731-1, Programming languages, environments and system software interfaces, Extensions to the C Library, Part I: Bounds-checking interfaces

Parameters

[out]	dest	pointer to string that will be replaced by src.
[in]	dmax	restricted maximum length of dest
[in]	src	pointer to the null terminated string that will be copied into the character array pointed to by dest
[in]	slen	maximum length of src

Precondition: Neither dest nor src shall be a null pointer.; dmax shall not equal zero.; dmax shall not be greater than RSIZE_MAX_STR.; slen shall not equal zero before C11. Since C11 zero is allowed.; slen shall not exceed dmax; Copying shall not take place between objects that overlap.

Returns: If there is a runtime-constraint violation, then if dest is not a null pointer and dmax is greater than zero and not greater than RSIZE_MAX_STR, then strcpyfldin_s nulls dest

Return values

EOK	when successful operation
ESNULLP	when dest/src is NULL pointer
ESZEROL	when dmax = 0. Before C11 also with slen = 0
ESLEMAX	when dmax > RSIZE_MAX_STR
ESOVRLP	when strings overlap
ESNOSPC	when dmax < slen
