beginthreadex 例子
基础知识:
|
在msdn中这样的例子:
是关于_beginthreadex的
// crt_begthrdex.cpp
// compile with: /MT
#include <windows.h>
#include <stdio.h>
#include <process.h>
unsigned Counter;
unsigned __stdcall SecondThreadFunc( void* pArguments )
{
printf( "In second thread...\n" );
while ( Counter < 1000000 )
Counter++;
_endthreadex( 0 );
return 0;
}
int main()
{
HANDLE hThread;
unsigned threadID;
printf( "Creating second thread...\n" );
// Create the second thread.
hThread = (HANDLE)_beginthreadex( NULL, 0, &SecondThreadFunc, NULL, 0, &threadID ); //NULL表示无传递参数
// Wait until second thread terminates. If you comment out the line
// below, Counter will not be correct because the thread has not
// terminated, and Counter most likely has not been incremented to
// 1000000 yet.
WaitForSingleObject( hThread, INFINITE );
printf( "Counter should be 1000000; it is-> %d\n", Counter );
// Destroy the thread object.
CloseHandle( hThread );
}
=======================
有传递参数:
#include <windows.h>
#include <stdio.h>
#include <process.h> typedef struct play_s
{
int sliderRange; } Play_Param;
unsigned Counter;
unsigned __stdcall SecondThreadFunc( void* pArguments )
{
Play_Param *pp = (Play_Param *) pArguments; int aa = pp->sliderRange;
while ( Counter < 1000000 )
Counter++;
_endthreadex( 0 );
return 0;
}
int main()
{
HANDLE hThread;
Play_Param param; param.sliderRange = 1000;
hThread = (HANDLE)_beginthreadex( NULL, 0, &SecondThreadFunc, ¶m, 0, NULL);//¶m表示传递参数
WaitForSingleObject( hThread, INFINITE );
CloseHandle( hThread );
} ---------------------
void Start(Play_Param *param)
{
setState(RUN);//设置运行标示 if( hThread == 0 && ::WaitForSingleObject(hThread ,1) == WAIT_TIMEOUT) //判断是否在运行 hThread = (HANDLE)_beginthreadex( NULL, 0, &SecondThreadFunc, param, 0, NULL );
