PsGetProcessId function (ntddk.h)

  • Article

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

Syntax

HANDLE PsGetProcessId(
  [in] PEPROCESS Process
);

Parameters

[in] Process

A pointer to a process object structure.

Return value

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

Remarks

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.
