这个代码每次循环都会创建一个进程，我在进程创建后都CloseHandle，但是任务管理器依然是在每次循环都增加一个句柄数





#include <stdio.h>

#include <windows.h>



int main(void)

{

	BOOL		StartUpStatus;

	STARTUPINFO	StartUpInfo;

	PROCESS_INFORMATION ProcessInfo;

	int			ExitCode = -1;



	while(1)

	{



		memset(&StartUpInfo, 0, sizeof(StartUpInfo));

		StartUpInfo.cb = sizeof(StartUpInfo);



		StartUpInfo.lpReserved = NULL;

		StartUpInfo.lpDesktop = NULL;

		StartUpInfo.lpTitle = NULL;

		StartUpInfo.dwFlags = STARTF_USESHOWWINDOW;

		StartUpInfo.wShowWindow = SW_HIDE;

		StartUpInfo.cbReserved2 = 0;

		StartUpInfo.lpReserved2 = NULL;

		memset(&ProcessInfo, 0, sizeof(ProcessInfo));



		StartUpStatus = CreateProcess(NULL, "cmd /c exit", NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &StartUpInfo, &ProcessInfo);



		if( StartUpStatus == FALSE )

		{

			return 1;

		}



		WaitForSingleObject(ProcessInfo.hProcess, INFINITE);



		GetExitCodeProcess(ProcessInfo.hProcess, (PDWORD)&ExitCode);



		CloseHandle(ProcessInfo.hThread);

		printf("%d\n", (int)GetLastError());

	

		CloseHandle(ProcessInfo.hProcess);

		printf("%d\n", (int)GetLastError());



		Sleep(2000);



	}



	return 0;
