fstrcspn

#include <string.h>

int fstrcspn (
  const char far *src,    /* source string */
  const char far *set);   /* characters to find */

The fstrcspn function searches the src string for any of the characters in the set string.

Note

• This function uses far pointers to objects and may be used in any memory model other than Tiny Model.

The fstrcspn function returns the index of the first character located in src that matches a character in set. If the first character in src matches a character in set, a value of 0 is returned. If there are no matching characters in src, the length of the src is returned.
