PROCESS_INFOMATION结构

typedef struct{

HANDLE hProcess; //新建进程的内核句柄

HANDLE hThread; //新建进程中主线程的内核句柄

DWORD dwProcessId; //新建进程的ID

DWORD dwThreadId; //新建进程主线程ID

}PROCESS_INFOMATION,*LPPROCESS_INFOMATION;

PROCESS_INFOMATION结构主要在新建进程函数CreateProcess中使用用来返回新建进程的相关信息。

例子：

int main(int argc,char* argv[])

{

char szCommandLine[] = "cmd";

STARTUPINFO si = {sizeof(si)};

PROCESS_INFOMATION pi; // 创建PROCESS_INFOMATION实例

si.dwFlags = START_USESHOWWINDOW;

si.wShowWindow = TRUE;

BOOL bRet = ::CreateProcess(

NULL,

szCommandLine,

NULL,

NULL,

FALSE,

CREATE_NEW_CONSOLE,

NULL,

NULL,

&si,

&pi); // 用pi返回新建进程的相关信息

if(bRet)

{

::CloseHandle(pi.hThreadId);

::CloseHandle(pi.hProcessId);

printf("新建进程的进程ID号：%d\",pi.dwProcessId);

printf("新建进程的主线程ID号：%d\",pi.dwThreadId);

}

return 0;
