PROCESS_INFORMATION Structure

Contains information about a newly created process and its primary thread. It is used with the CreateProcess, CreateProcessAsUser, CreateProcessWithLogonW, or CreateProcessWithTokenW function.

typedef struct _PROCESS_INFORMATION {
  HANDLE hProcess;
  HANDLE hThread;
  DWORD dwProcessId;
  DWORD dwThreadId;
} PROCESS_INFORMATION, 
 *LPPROCESS_INFORMATION;

Members

hProcess

A handle to the newly created process. The handle is used to specify the process in all functions that perform operations on the process object.

hThread

A handle to the primary thread of the newly created process. The handle is used to specify the thread in all functions that perform operations on the thread object.

dwProcessId

A value that can be used to identify a process. The value is valid from the time the process is created until all handles to the process are closed and the process object is freed; at this point, the identifier may be reused.

dwThreadId

A value that can be used to identify a thread. The value is valid from the time the thread is created until all handles to the thread are closed and the thread object is freed; at this point, the identifier may be reused.
