acl_get_qualifier - Retrieves the tag qualifier (ID) for
an ACL entry
#include <sys/acl.h>
void * acl_get_qualifier(
acl_entry_t entry_d );
Security Library (libpacl.a)
Designates the working storage internal representation ACL
entry to retrieve the tag qualifier from.
NOTE: This function is based on Draft 13 of the POSIX
P1003.6 standard.
The acl_get_qualifier() function retrieves ACL entry tag
qualifier, which is the user or group ID associated with
the entry. If the entry tag type is ACL_USER, a *uid_t is
returned. If the tag type is ACL_GROUP, a *gid_t is
returned. For all other tag types, NULL is returned.
Upon successful completion, the acl_get_qualifier() function
returns a pointer to the ACL entry tag qualifier.
Otherwise, a value of NULL is returned and errno is set to
indicate the error.
If any of the following conditions occur, the
acl_get_qualifier() function sets errno to the corresponding
value:
Argument entry_d does not refer to a valid ACL entry.
The value of the tag type in ACL entry referred to
by entry_d is ACL_USER_OBJ, ACL_GROUP_OBJ, or
ACL_OTHER_OBJ.
