25-进程的创建和使用

进程的创建和使用

函数CreateProcess来创建进程

参数：

  • lpCommandLine：打开进程的路径（主要配置的参数）

  • 其余保持默认即可（详见下面示例）

返回值：

  • 成功为1

  • 失败使用GetLastError()查看对应的错误码

案例

#include<stdio.h>
#include<Windows.h>

int RunExe()
{
	TCHAR szCommandLine[] = L"C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe";
	STARTUPINFO strStartupInfo;
	memset(&strStartupInfo, 0, sizeof(STARTUPINFO));
	strStartupInfo.cb = sizeof(strStartupInfo);
	PROCESS_INFORMATION	szProcessInformation;
	memset(&szProcessInformation, 0, sizeof(PROCESS_INFORMATION));

	int bRet = CreateProcess(
		NULL,
		szCommandLine,
		NULL,
		NULL,
		FALSE,
		CREATE_NEW_CONSOLE,
		NULL,
		NULL,
		&strStartupInfo,
		&szProcessInformation
	);

	if (bRet)
	{
		printf("CreateSucess bRet = %d", bRet);
		WaitForSingleObject(szProcessInformation.hProcess, 3000);
		CloseHandle(szProcessInformation.hProcess);
		CloseHandle(szProcessInformation.hThread);
		szProcessInformation.hProcess = NULL;
		szProcessInformation.hThread = NULL;
		szProcessInformation.dwProcessId = NULL;
		szProcessInformation.dwThreadId = NULL;
	}
	else
	{
		printf("Create Failed bRet = %d", bRet);
		printf("errorcode = %d", GetLastError());
	}
	return 0;
}


int main()
{
	printf("This is Chrome");
	RunExe();
	system("pause");
}
