Parameters

[in]	dest	pointer to string to determine the prefix
[in]	dmax	restricted maximum length of string dest
[in]	src	pointer to exclusion string
[in]	slen	restricted maximum length of string src
[out]	count	pointer to a count variable that will be updated with the dest substring length

Precondition

Neither dest nor src shall be a null pointer.

count shall not be a null pointer.

Neither dmax nor slen shall not be 0.

Neither dmax nor slen shall not be greater than RSIZE_MAX_STR.

Return values

EOK	when successful operation, substring found.
ESNULLP	when dest/src/substring is NULL pointer
ESZEROL	when dmax/slen = 0
ESLEMAX	when dmax/slen > RSIZE_MAX_STR
