-description

The FltGetRequestorProcessId routine returns the unique 32-bit process ID for the process associated with the thread that requested a given I/O operation.

-parameters

-param CallbackData [in]

Pointer to the callback data structure (FLT_CALLBACK_DATA) for the I/O operation.

-returns

FltGetRequestorProcessId returns the process ID for the process associated with the thread that originally requested the I/O operation. If the operation is not associated with any thread, FltGetRequestorProcessId returns zero.

-remarks

FltGetRequestorProcessId returns the process ID for the process that the requesting thread is currently attached to. This process may or may not be the same process that created the thread.
