學習筆記：windows下，用c語言來創建線程

#include <stdio.h>
#include <windows.h>

typedef void * HANDLE;
#define SEMAPHORE HANDLE
#define THREADHANDLE HANDLE
#define THREADPROCESS DWORD WINAPI
#define THREADRETURN 0
#define PTHREADPROCESS LPTHREAD_START_ROUTINE
#define NULLTHREAD NULL

int g_thread_end = 0;

THREADHANDLE os_creatthread(PTHREADPROCESS fun,void *para)
{
 unsigned long id;
 return CreateThread(NULL,0,fun,para,0,&id);
}
void waitforthread()
{
 while (g_thread_end == 0)
 {
  NULL;
 }
}
THREADPROCESS threadfun(PVOID arg)
{
 int i;
 for(i=0; i < 0xfffffff; i++)
 {
  NULL;
 }
 g_thread_end = 1;
 return 0;
}

void main()
{
 THREADHANDLE pthread = NULLTHREAD;

 printf("Creating thread.../n");
 pthread = os_creatthread(threadfun,NULL);
 printf("Creating thread completed.Handle:%x/n",pthread);

 printf("Waiting for thread.../n");
 waitforthread();
 printf("Waiting ended./n");
}

/*在Windows下面，用CreateThread(LPSECURITY_ATTRIBUTES   lpThreadAttributes,  
                                                              DWORD   dwStackSize,  
                                                              LPTHREAD_START_ROUTINE   lpStartAddress,  
                                                              LPVOID   lpParameter,  
                                                              DWORD   dwCreateionFlags,  
                                                              LPDWORD   lpThreadId)  
  函數可以創建一個線程,第一個參數指線程的安全屬性的設定，第二個參數表示線程堆棧的大小，第三個參數表示線程函數名稱，第四個參數線程執行的參數，第五個參數指線程的優先級，最後一個參數指向線程的ID。關於windows下用C創建多線程可以查查MSDN即可。
