DLBINDACK(9F)							 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 success‐
			    fully.

       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 asso‐
			    ciated 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 formu‐
       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.
