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.
