STRCSPN(3)                OpenBSD Programmer's Manual               STRCSPN(3)

     strcspn - span the complement of a string

     #include <string.h>

     strcspn(const char *s, const char *charset);

     The strcspn() function spans the initial part of the null-terminated
     string s as long as the characters from s do not occur in string charset
     (it spans the complement of charset).

     The strcspn() function returns the number of characters spanned.

     The following call to strcspn() will return 3, since the first three
     characters of string s do not occur in string charset:

           char *s = "foobar";
           char *charset = "bar";
           size_t span;

           span = strcspn(s, charset);

     memchr(3),  strchr(3),  strpbrk(3),  strrchr(3),  strsep(3),  strspn(3),
     strstr(3),  strtok(3)

     The strcspn() function conforms to ANSI X3.159-1989 (``ANSI C'').
