NAME
     Set_Environment - set a tool's environment

SYNOPSIS
     Set_Environment(in string variable,
                     in string value
                     [...]);

DESCRIPTION
     The Set_Environment request replaces the value of the  indi-
     cated environment variable(s).

     The variable argument is the name of the  environment  vari-
     able to set.

     The value argument is the value of the environment variable.
     If  this  argument  is unset (in other words, has a value of
     (char *)0), then the variable should  be  removed  from  the
     environment.   It  is  not  an error for the variable not to
     have existed in the first place.

APPLICATION USAGE
     The ttdt_session_join(3), function can be used  to  register
     for, and transparently process, the Set_Environment request.

EXAMPLES
     The Set_Environment request can be sent as in the  following
     example:

          Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
                      the_recipient_procid, TTDT_SET_ENVIRONMENT,
                      my_callback);
          tt_message_arg_add(msg, TT_IN, Tttk_string, "PATH");
          tt_message_arg_add(msg, TT_IN, Tttk_string, "/bin:/usr/ucb");
          tt_message_send(msg);

WARNINGS
     Set_Environment can also be sent as a multicast  notice,  as
     an  edict  to  all  tools  in the scope of the message.  The
     consequences of doing so can be severe and unexpected.
