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.
