SYNOPSIS

#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 constraints.
