strcspn

Syntax

#include <string.h> size_t strcspn(const char *s1, const char *set);

Description

This function finds the first character in s1 that matches any character in set. Note that the NULL bytes at the end of each string counts, so you'll at least get a pointer to the end of the string if nothing else.

The index of the found character.
