dlpi_fd(3DLPI)	Data Link Provider Interface Library Functions	dlpi_fd(3DLPI)

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 addi‐
       tional 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.
