IoIncrementKeepAliveCount function

-description

The IoIncrementKeepAliveCount routine increments a reference count associated with a Windows app process on a specific device. This routine is called by a kernel mode driver in response to the app opening a process for I/O. This prevents Windows from suspending the app before the I/O process is complete.

-parameters

-param FileObject [in, out]

The file object handle to the device.

-param Process [in, out]

The process associated with the device.

-returns

This routine returns STATUS_SUCCESS on success, or the appropriate NTSTATUS error code on failure. NTSTATUS error codes are defined in Ntstatus.h.
