NAME
       dlpi_fd - get DLPI file descriptor

SYNOPSIS
       cc [ flag ... ] file ... -ldlpi [ library ... ]
       #include <libdlpi.h>

       int dlpi_fd(dlpi_handle_t dh);

DESCRIPTION
       The dlpi_fd() function returns the integer file descriptor that can be used to directly operate on the open DLPI stream associated with the
       DLPI handle dh. This file descriptor can be used to perform non-DLPI operations that do not alter the state of the  DLPI  stream,  such	as
       waiting	for  an  event	using  poll(2),  or  pushing and configuring additional STREAMS modules, such as pfmod(7M). If DLPI operations are
       directly performed on the file descriptor, or a STREAMS module is pushed that alters the message-passing interface such	that  DLPI  opera-
       tions can no longer be issued, future operations on dh might not behave as documented.

       The returned file descriptor is managed by libdlpi(3LIB) and the descriptor must not be closed.

RETURN VALUES
       The function returns the integer file descriptor associated with the DLPI handle dh. If dh is invalid, -1 is returned.
