EXPORT errno_t memchr_s	(	const void *restrict	dest,
		rsize_t	dlen,
		const int	ch,
		void **	result
	)

Finds the first occurrence of ch (after conversion to unsigned char as if by (unsigned char)ch) in the null-terminated buffer pointed to by dest (each character interpreted as unsigned char).

Remarks

IMPLEMENTED IN

Parameters

[in]	dest	pointer to buffer to compare against
[in]	dlen	length of dest to search in
[in]	ch	character to search for
[out]	result	pointer to result in dest

Precondition

Neither dest nor result shall be a null pointer.

dlen shall not be 0.

dlen shall not be greater than RSIZE_MAX_MEM.

ch shall not be greater than 255

Return values

EOK	when successfully character found.
ESNULLP	when dest/result is a NULL pointer
ESZEROL	when dlen = 0
ESLEMAX	when dlen > RSIZE_MAX_STR
ESLEMAX	when ch > 255
ESNOTFND	when ch not found in dest
