STRSPN(3)               NetBSD Library Functions Manual              STRSPN(3)

NAME
     strspn -- span a string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     size_t
     strspn(const char *s, const char *charset);

DESCRIPTION
     The strspn() function spans the initial part of the nul-terminated string
     s as long as the characters from s occur in string charset.

RETURN VALUES
     The strspn() function returns the number of characters spanned.

EXAMPLES
     The following call to strspn() will return 3, since the first three char-
     acters of string s are part of string charset:

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

           span = strspn(s, charset);
