SYNOPSIS


.In string.h size_t strcspn "const char *s" "const char *charset"

DESCRIPTION

The strcspn function spans the initial part of the null-terminated string s as long as the characters from s do not occur in string charset (it spans the complement of charset). In other words, it computes the string array index in s of the first character of s which is also in charset, else the index of the first null character.

RETURN VALUES

The strcspn function returns the number of characters spanned.
