SCCS: @(#)dcancel.c 1.9 98/08/28 TETware release 3.3
NAME: dcancel.c
PRODUCT: TETware
AUTHOR: Andrew Dingwall, UniSoft Ltd.
DATE CREATED: June 1997
DESCRIPTION:
API library functions for cancelling test purposes.
This version of this file replaces a previous one of the same
name.
The API functions provided here perform the same actions as
those provided in the previous file, but the implementation is
different.
Re-implementation of these functions became necessary with the
introduction of the defined test case interface.
MODIFICATIONS:
Andrew Dingwall, UniSoft Ltd., July 1998
Added support for shared API libraries.
