/************************************************************************

SCCS:   	@(#)titcmenv.c	1.9 98/09/01 TETware release 3.3
NAME:		titcmenv.c
PRODUCT:	TETware
AUTHOR:		Andrew Dingwall, UniSoft Ltd.
DATE CREATED:	April 1992

DESCRIPTION:
	function to put transport-independent arguments in the environment to
	be received by the tcm

MODIFICATIONS:
	Andrew Dingwall, UniSoft Ltd., October 1992
	Modified so as to allow tet_ti_tcmputenv() to be called from
	TCMs as well as from TCCs - this is required by tet_exec().

	Geoff Clare, UniSoft Ltd., August 1996
	Missing <string.h>.

	Andrew Dingwall, UniSoft Ltd., July 1998
	Added support for shared API libraries.

	Aaron Plattner, April 2010
	Fixed warnings when compiled with GCC's -Wall option.
