WaitForMultipleObjects 到底什么意思, 什么作用? 请看代码
#include <iostream>#include <windows.h>using namespace std;#define MAX_SEM_COUNT 10#define THREADCOUNT 12HANDLE ghSemaphore;DWORD WINAPI ThreadProc( LPVOID );void main(){ HANDLE aThread[THREADCOUNT]; DWORD ThreadID; int i; // Create a semaphore with initial and max counts of MAX_SEM_COUNT ghSemaphore = CreateSemaphore( NULL, // default security attributes MAX_SEM_COUNT, // initial count MAX_SEM_COUNT, // maximum count NULL); // unnamed semaphore if (ghSemaphore == NULL) { printf("CreateSemaphore error: %d\n", GetLastError()); return; } // Create worker threads for( i=0; i < THREADCOUNT; i++ ) { aThread[i] = CreateThread( NULL, // default security attributes 0, // default stack size (LPTHREAD_START_ROUTINE) ThreadProc, NULL, // no thread function arguments 0, // default creation flags &ThreadID); // receive thread identifier if( aThread[i] == NULL ) { printf("CreateThread error: %d\n", GetLastError()); return; } } // Wait for all threads to terminate WaitForMultipleObjects(THREADCOUNT, aThread, TRUE, INFINITE); // 这个函数到底是什么作用? 什么叫做等待内核对象? // Close thread and semaphore handles for( i=0; i < THREADCOUNT; i++ ) CloseHandle(aThread[i]); CloseHandle(ghSemaphore);}DWORD WINAPI ThreadProc( LPVOID lpParam ){ BOOL bContinue=TRUE; while(bContinue) {} return TRUE;}
