.Sh NAME
.Nm acl_set_qualifier
.Nd set ACL tag qualifier
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In sys/types.h
.In sys/acl.h
.Ft int
.Fn acl_set_qualifier "acl_entry_t entry_d" "const void *tag_qualifier_p"
.Sh DESCRIPTION
The
.Fn acl_set_qualifier
function
is a POSIX.1e call that sets the qualifier of the tag for the ACL entry
.Fa entry_d
to the value referred to by
.Fa tag_qualifier_p .
.Pp
The tag type of the ACL entry, as previously set with
.Xr acl_set_tag_type 3 ,
must be either
.Dv ACL_EXTENDED_ALLOW
or
.Dv ACL_EXTENDED_DENY ,
and
.Fa tag_qualifier_p
should be a pointer to a global unique identifier (of type
.Ft guid_t ) .
.Sh RETURN VALUES
.Rv -std acl_set_qualifier
.Sh ERRORS
The
.Fn acl_set_qualifier
function fails if:
.Bl -tag -width Er
.It Bq Er EINVAL
Argument
.Fa entry_d
is not a valid descriptor for an ACL entry.  The tag type of the
ACL entry
.Fa entry_d
is not
.Dv ACL_EXTENDED_ALLOW
or
.Dv ACL_EXTENDED_DENY .
The value pointed to by
.Fa tag_qualifier_p
is not valid.
.It Bq Er ENOMEM
The value to be returned requires more memory than is allowed
by the hardware or system-imposed memory management constraints.
