acl_get_tag

Synopsis:

#include <sys/acl.h>

int acl_get_tag_type( acl_entry_t entry_d,
                      acl_tag_t *tag_type_p );

entry_d

The descriptor of the entry that you want to get the tag type of.

tag_type_p

A pointer to a location where the function can store the tag type; one of the following:

ACL_GROUP — a named group.
ACL_GROUP_OBJ — the owning group.
ACL_MASK — the maximum permissions allowed for named users, named groups, and the owning group.
ACL_OTHER — users whose process attributes don't match any other ACL entry; the "world".
ACL_USER — named users.
ACL_USER_OBJ — the owning user.

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

The acl_get_tag_type() function gets the tag type from an ACL entry and stores it in the location pointed to by tag_type_p.

0, or -1 if an error occurred (errno is set, and the location pointed to by tag_type_p isn't changed).

This function is based on the withdrawn POSIX draft P1003.1e.
