3.4.2 语音播报线程的建立
如下如下为线程创建程序和线程服务程序代码
int ThreadProcTest(LPVOID lpParameter)
{
while(glThreadFlag)//线程运行标志
{
Read_Alarm();//语音播报子程序
Sleep(1000);
}
return 0;
}
int CreateAppThreadTeat() //线程构建函数
{
SECURITY_ATTRIBUTES secAttr;
DWORD id=0;
secAttr.nLength = sizeof(SECURITY_ATTRIBUTES); //长度
secAttr.bInheritHandle = false; //继承句柄
secAttr.lpSecurityDescriptor = NULL; //安全描述
glAppTreadHandle = CreateThread(&secAttr,0,(LPTHREAD_START_ROUTINE)ThreadProcTest,NULL,0,&id); //创建线程句柄
return 0;
}
