NAME
strspn, strcspn -- span a string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h> size_t strspn(const char *s, const char *charset); size_t strcspn(const char *s, const char *charset);
DESCRIPTION
The strspn() function spans the initial part of the null-terminated string s as long as the characters from s occur in the null-terminated string charset. In other words, it computes the string array index of the first character of s which is not in charset, else the index of the first null character. The strcspn() function spans the initial part of the null-terminated string s as long as the characters from s do not occur in the null-ter- minated string charset (it spans the complement of charset). In other words, it computes the string array index of the first character of s which is also in charset, else the index of the first null character.
RETURN VALUES
The strspn() and strcspn() functions return the number of characters spanned.
