Syntax

ULONGLONG PsGetProcessStartKey(
  [in] PEPROCESS Process
);

Parameters

[in] Process

A pointer to the EPROCESS structure that represents the process. Drivers can use the PsGetCurrentProcess and ObReferenceObjectByHandle routines to obtain a pointer to the EPROCESS structure for a process.
