NAME
     Get_Environment - 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.
