SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_set_qualifier(acl_entry_t entry_d, const void *tag_qualifier_p);

DESCRIPTION
     The acl_set_qualifier() function is a POSIX.1e call that sets the qualifier of the tag for the ACL entry entry_d to the value referred to by
     tag_qualifier_p.

RETURN VALUES
     The acl_set_qualifier() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set
     to indicate the error.

ERRORS
     The acl_set_qualifier() function fails if:

     [EINVAL]		Argument entry_d is not a valid descriptor for an ACL entry.  The tag type of the ACL entry entry_d is not ACL_USER or
			ACL_GROUP.  The value pointed to by tag_qualifier_p is not valid.

     [ENOMEM]		The value to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.
