Function Documentation

strcmpfld_s()

errno_t strcmpfld_s	(	const char *	dest,
		rsize_t	dmax,
		const char *	src,
		int *	indicator
	)

Compares the character array pointed to by src to the character array pointed to by dest for dmax characters.

The null terminator does not stop the comparison.

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

[in]	dest	pointer to string to compare against
[in]	dmax	restricted maximum length of string dest
[in]	src	pointer to the string to be compared to dest
[out]	indicator	pointer to result indicator, greater than 0, equal to 0 or less than 0, if the string pointed to by dest is greater than, equal to or less than the string pointed to by src respectively.

Precondition

Neither dest nor src shall be a null pointer.

indicator shall not be a null pointer.

dmax shall not be 0

dmax shall not be greater than RSIZE_MAX_STR

Returns

indicator (when the return code is OK)

Return values

>0	when dest greater than src
0	when strings the same
<0	when dest less than src
EOK	when comparison is complete
ESNULLP	when dest/src/indicator is NULL pointer
ESZEROL	when dmax = 0
ESLEMAX	when dmax > RSIZE_MAX_STR
