STARTUPINFO for a characteristic structure of the main window to specify a new process. (IN parameter)

 The main details are stored to create a variety of child process

PROCESS_INFORMATION (OUT parameter)

PROCESS_INFORMATION structure

typedef struct_PROCESS_INFORMATION{

HANDLE hProcess;

HANDLE hThread;

DWORD dwProcessId;

DWORD dwThreadId;

}PROCESS_INFORMATION;

Where the members have the following meanings.

① hProcess: returns a handle to the new process.

② hThread: return to the main thread handle.

③ dwProcessId: Returns a global process identifier . This identifier is used to identify a process. The process is

Created to termination, the value is always valid.

④ dwThreadId: Returns a global thread identifier. This identifier is used to identify a thread. From the thread is hit

Built to terminate, the value is always valid.
