Count the characters at the beginning of a string that aren't in a given character set
#include <string.h>
size_t strcspn( const char* str,
const char* charset );
- str
- The string that you want to search.
- charset
- The set of characters you want to look for.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The strcspn() function finds the length of the initial segment
of the string pointed to by str that consists entirely of
characters not from the string pointed to by charset.
The terminating NUL character isn't considered part of
str.
The length of the initial segment.
