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);
