The PsGetProcessId routine returns the process identifier (process ID) that is associated with a specified process.

HANDLE
  PsGetProcessId(
    IN PEPROCESS  Process
    );

Parameters

Process

A pointer to a process object structure.

Return Value

PsGetProcessId returns the process ID of the process that the Process parameter specifies.

Comments

The EPROCESS-typed process object structure is an opaque data structure that the operating system uses internally. To obtain a pointer to the EPROCESS structure for the current process, a driver can call PsGetCurrentProcess. To obtain a pointer to the EPROCESS structure for a different process, the driver can call ObReferenceObjectByHandle.

Requirements

Versions: PsGetProcessID is available on Windows XP and later versions of Windows.

IRQL: Any level

Headers: Declared in Ntddk.h. Include Ntddk.h.
