SCCS:   	@(#)dtcm.c	1.33 98/09/01 TETware release 3.3
NAME:		'C' Test Case Manager
PRODUCT:	TETware
AUTHOR:		Geoff Clare, UniSoft Ltd.
DATE CREATED:	23 July 1990
SYNOPSIS:

	int tet_tcm_main(int argc, char **argv);
	int tet_thistest;

DESCRIPTION:

	Tcm_main() is the main program for the Test Case Manager (TCM),
	called from a different main() wrapper for each API.
	The command line contains the invocable components (IC's) to be
	executed.  All test purposes in the user-supplied tet_testlist[]
	array with an icref element corresponding to one of the requested
	IC's are called, preceded by a call to the function pointed to
	by tet_startup and followed by tet_cleanup (if each is not NULL).
	The TCM reads configuration variables from the file specified
	by the environment variable TET_CONFIG, provides handling of
	unexpected signals on UNIX-like platforms, and reports the start
	and end of IC's and the start of test purposes.

	Tet_thistest is set to the test purpose number during execution
	of each test purpose.  Test purposes are numbered in the sequence
	of the tet_testlist[] array (starting at 1) regardless of
	execution sequence.

MODIFICATIONS:

	Geoff Clare, UniSoft Ltd, 6 Sept 1990
		New results file format.
		If no arguments assume all ICs.
		Move tet_error() to resfile.c.
		Change handling of ICs with zero TPs.

	Geoff Clare, UniSoft Ltd, 28 Sept 1990
		When doing all ICs start from lowest defined IC instead of 1.
	
	Geoff Clare, UniSoft Ltd, 28 Nov 1990
		Add tet_nosigreset.
	
	Geoff Clare, UniSoft Ltd, 6 Sept 1991
		Add call to tet_delreas().

	DTET development - this file is based on release 1.10 of the TET
	David G. Sawyer and John-Paul Leyland, UniSoft Ltd, June 1992

	Andrew Dingwall, UniSoft Ltd., October 1992
	Moved tet_root[] and setup to tcmfuncs.c so that tcmchild
	processes can see it as well.

	Updated Abort, Delete and results processing to work in a DTET
	environment.

	Geoff Clare, UniSoft Ltd, July-August 1996
	Changes for TETWare.

	Andrew Dingwall, UniSoft Ltd., August 1996
	changes for use with tetware tcc

	Geoff Clare, UniSoft Ltd, Sept 1996
	Added call to tet_init_blockable_sigs().
	Changes for TETWare-Lite.

	Geoff Clare, UniSoft Ltd., Oct 1996
	Use TET_THR_EQUAL() to compare thread IDs.
	Restructured tcm source to avoid "ld -r".

	Andrew Dingwall, UniSoft Ltd., June 1997
	Changes to support the defined interface between the TCM and
	the test case.
	Changed the sigsetjmp()/siglongjmp() code so that the signal number
	is passed back in a global variable rather than by using the 2nd
	argument to siglongjmp();
	(apparently the only thing that can be done with the return value of
	sigsetjmp() is to perform a comparison on it - for maximum portability
	it should not be assigned to a variable).

	Geoff Clare, UniSoft Ltd., July 1997
	Changes to support NT threads.

	Andrew Dingwall, UniSoft Ltd., January 1998
	Permit the iclist to include IC 0.

	Andrew Dingwall, UniSoft Ltd., February 1998
	Use TETware-specific macros to access threads functions and
	data items.
	Handle an empty iclist correctly.

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