tt_message_gid(3)	      ToolTalk Functions	     tt_message_gid(3)

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.

       The application should check the tt_message_uid(3) and tt_message_gid()
       against the User ID and Group ID of the application receiving the mess‐
       sage. If the UID and/or GID of the application do not match that of the
       message then the receiving application should consider failing the mes‐
       sage with TT_DESKTOP_EACCES.

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_c(5), tt_message_uid(3).
