    1.18 +* FUNCTION
    1.19 +* <<strcspn>>---count chars not in string
    1.20 +* INDEX
    1.21 +* strcspn
    1.22 +* ANSI_SYNOPSIS
    1.23 +* size_t strcspn(const char *<[s1]>, const char *<[s2]>);
    1.24 +* TRAD_SYNOPSIS
    1.25 +* size_t strcspn(<[s1]>, <[s2]>)
    1.26 +* char *<[s1]>;
    1.27 +* char *<[s2]>;
    1.28 +* This function computes the length of the initial part of
    1.29 +* the string pointed to by <[s1]> which consists entirely of
    1.30 +* characters <[NOT]> from the string pointed to by <[s2]>
    1.31 +* (excluding the terminating null character).
    1.32 +* RETURNS
    1.33 +* <<strcspn>> returns the length of the substring found.
    1.34 +* PORTABILITY
    1.35 +* <<strcspn>> is ANSI C.
    1.36 +* <<strcspn>> requires no supporting OS subroutines.

    1.49 +The search includes terminating null-characters, so the function
