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  for-
       mulating 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 unsuccessfull 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 or interrupt context.
