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
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.
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);
