NAME
       tt_message_gid — retrieve the group identifier attribute from a message

SYNOPSIS
       #include <Tt/tt_c.h>
       gid_t tt_message_gid(
       Tt_message m);

DESCRIPTION
       The  tt_message_gid  function  retrieves the group identifier attribute
       from the specified message.

       The ToolTalk service automatically sets the group identifier of a  mes‐
       sage with the group identifier of the process that created the message.

       The  m  argument	 is the opaque handle for the message involved in this
       operation.

RETURN VALUE
       Upon successful completion, the	tt_message_gid	function  returns  the
       group  identifier of the message.  If the group nobody is returned, the
       message handle is not valid.

SEE ALSO
       Tt/tt_c.h - Tttt_c(5), tt_message_uid(3).
