dlbindack(9F)		 Kernel Functions for Drivers		 dlbindack(9F)

NAME
       dlbindack,  dlphysaddrack,  dlokack,  dlerrorack,  dluderrorind	- DLPI
       device driver helper functions

SYNOPSIS
       #include <sys/dlpi.h>

       void dlokack(queue_t *wq, mblk_t *mp, t_uscalar_t correct_primitive);

       void dlerrorack(queue_t *wq, mblk_t *mp,	 t_uscalar_t  error_primitive,
       t_uscalar_t error, t_uscalar_t unix_errno);

       void  dlbindack(queue_t	*wq,  mblk_t  *mp,  t_scalar_t sap, const void
       *addrp,	t_uscalar_t  addrlen,  t_uscalar_t   maxconind,	   t_uscalar_t
       xidtest);

       void   dlphysaddrack(queue_t   *wq,  mblk_t  *mp,  const	 void  *addrp,
       t_uscalar_t addrlen);

       void  dluderrorind(queue_t  *wq,	 mblk_t	 *mp,	const	void   *addrp,
       t_uscalar_t addrlen, t_uscalar_t error, t_uscalar_t unix_errno);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       wq

	   Streams write queue.

       mp

	   Pointer to the bind request message.

       sap

	   Service access point being requested.

       addrp

	   Pointer to the dlpi layer source address.

       addrlen

	   Size of the dlpi layer address pointed to by addr.

       maxconind

	   Maximum number of DL_CONNECT_IND messages allowed to be outstanding
	   per stream.

       xidtest

	   The XID and TEST responses supported.

       correct_primitive

	   Identifies the DL primitive completing successfully.

       error_primitive

	   Identifies the DL primitive in error.

       error

	   DLPI error associated with the failure in the DLPI request.

       unix_errno

	   Corresponding UNIX system error that can  be	 associated  with  the
	   failure in the DLPI request.

DESCRIPTION
       All  functions  described in this manpage take a pointer to the message
       passed to the DLPI provider (mblk_t) and attempt to reuse it in	formuā€
       lating  the  M_PROTO  reply.  If	 the  message block is too small to be
       reused, it is freed and a new one is allocated.

       All functions reply upstream using  qreply(9F).	The  write-side	 queue
       pointer must be provided.

       The   dlokack()	 function  provides  the  successfull  acknowledgement
       DL_OK_ACK message reply to the DLPI provider and is  used  to  complete
       many of the DLPI requests in the DLPI consumer.

       The  dlerrorack()  function  provides the unsuccessfull acknowledgement
       DL_ERROR_ACK message reply to the DLPI provider and is used  for	 error
       completions were required for DLPI requests in the DLPI consumer.

       The  dlbindack() function provides the DL_BIND_ACK message reply to the
       DLPI provider and is used to complete the DL_BIND_REQ processing in the
       DLPI consumer.

       The  dlphysaddrack()  function  provides	 the  DL_PHYS_ADDR_ACK message
       reply used to complete the DL_PHYS_ADDR_ACK processing.

       The dluderrorind() function provides the DL_UDERROR_IND	message	 reply
       used to complete an unsuccessful DL_UNITDATA_REQ.

RETURN VALUES
       None.

NOTES
       These  functions	 are not required if you are are writing a DLPI device
       driver using gld(7D).

CONTEXT
       All DLPI helper functions can be called from user, interrupt, or kernel
       context.
