KRB5_ACL_MATCH_FILE(3)	 BSD Library Functions Manual	KRB5_ACL_MATCH_FILE(3)

NAME
     krb5_acl_match_file, krb5_acl_match_string — ACL matching functions

LIBRARY
     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS
     krb5_error_code
     krb5_acl_match_file(krb5_context context, const char *file,
	 const char *format, ...);

     krb5_error_code
     krb5_acl_match_string(krb5_context context, const char *string,
	 const char *format, ...);

DESCRIPTION
     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 match‐
     ing 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.

EXAMPLES
	   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");
	   }
	   free(s);
