◆ strcpyfldout_s()

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

The strcpyfldout_s function copies slen characters from the character array pointed to by src into the string pointed to by dest.

A null is included to properly termiante the dest string. The copy operation does not stop on the null character as function copies dmax characters.

Remarks: EXTENSION TO ISO/IEC TR 24731, 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 character array to be copied to dest and null terminated.
[in]	slen	the maximum number of characters that will be copied from the src field into the dest string.

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.; 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 strcpyfldout_s nulls dest
