NAME
     Get_Environment request - get a tool's environment

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

DESCRIPTION
     The Get_Environment request reports the value of  the  indi-
     cated environment variable(s).

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

     The value argument	is the value of	the environment	variable.
     If	no value (in other words, (char	*)0) is	returned for this
     argument, then the	variable was not present in the	handler's
     environment.   This  condition is not an error.  If an empty
     string (in	other words, "") is returned for  this	argument,
     then  the variable	was present in the handler's environment,
     but had a null value.

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

SEE ALSO
     ttdt_session_join(3); Set_Environment request.
