DESCRIPTION

21       The strcspn() function shall compute the length (in bytes) of the maxi‐

23       entirely of bytes not from the string pointed to by s2.
24

RETURN VALUE

26       The strcspn() function shall return the length of the computed  segment
27       of the string pointed to by s1; no return value is reserved to indicate
