KRB5_ACL_MATCH_FILE(3)		   BSD 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");
