HALCON中VB，C++，Ｃ三种编程的范例

/***************************************************************************** * example_multithreaded1.c ***************************************************************************** * * Project: HALCON/C * Description: simple example program which shows how to use * Parallel HALCON's reentrancy feature * for multithreaded applications; * note that this program is optimized for 2 processor machines; * therefore, it uses two threads which perform different * tasks of the application in parallel; * * under UNIX (Linux) compile this file via: * make parallel TEST_PROG=example_multithreaded * * NOTE: This program can only be used with Parallel HALCON; * thus it can only be compiled and executed on * architectures, which are supported by Parallel HALCON! * * (c) 1996-2000 by MVTec Software GmbH * www.mvtec.com ***************************************************************************** * * $Revision: 1.6 $ * $Date: 2003/11/10 14:52:04 $ * */ #ifdef WIN32 #include <windows.h> #include <process.h> #endif #include <stdio.h> #include <stdlib.h> #ifndef WIN32 #include <pthread.h> #endif #include "HalconC.h" /*****************************************************************************/ /* Global variables: */ int result0= H_MSG_TRUE;
