KRB5_ACL_MATCH_FILE(3)     Library Functions Manual     KRB5_ACL_MATCH_FILE(3)

     krb5_acl_match_file, krb5_acl_match_string - ACL matching functions

     Kerberos 5 Library (libkrb5, -lkrb5)

     krb5_acl_match_file(krb5_context context, const char *file,
         const char *format, ...);

     krb5_acl_match_string(krb5_context context, const char *string,
         const char *format, ...);

     krb5_acl_match_file matches ACL format against each line in a file.
     Lines starting with # are treated like comments and ignored.

     krb5_acl_match_string matches ACL format against a string.

     The ACL format has three format specifiers: s, f, and r.  Each specifier
     will retrieve one argument from the variable arguments for either
     matching or storing data.  The input string is split up using " " and
     "\t" as a delimiter; multiple " " and "\t" in a row are considered to be
     the same.

           s    Matches a string using strcmp(3) (case sensitive).

           f    Matches the string with fnmatch(3).  The flags argument (the
                last argument) passed to the fnmatch function is 0.

           r    Returns a copy of the string in the char ** passed in; the
                copy must be freed with free(3).  There is no need to free(3)
                the string on error: the function will clean up and set the
                pointer to NULL.

     All unknown format specifiers cause an error.

           char *s;

           ret = krb5_acl_match_string(context, "foo", "s", "foo");
           if (ret)
               krb5_errx(context, 1, "acl didn't match");
           ret = krb5_acl_match_string(context, "foo foo baz/kaka",
               "ss", "foo", &s, "foo/*");
           if (ret) {
               /* no need to free(s) on error */
               assert(s == NULL);
               krb5_errx(context, 1, "acl didn't match");
