16 The strspn() function calculates the length (in bytes) of the initial
17 segment of s which consists entirely of bytes in accept.
18
19 The strcspn() function calculates the length of the initial segment of
20 s which consists entirely of bytes not in reject.
21
23 The strspn() function returns the number of bytes in the initial seg‐
24 ment of s which consist only of bytes from accept.
25
26 The strcspn() function returns the number of bytes in the initial seg‐
27 ment of s which are not in the string reject.
