     gid_t tt_message_gid(Tt_message m);

DESCRIPTION

     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.
