DESCRIPTION

75       All functions described in this manpage take a pointer to  the  message
76       passed  to the DLPI provider (mblk_t) and attempt to reuse it in formu‐
77       lating the M_PROTO reply. If the message  block  is  too  small  to  be
78       reused, it is freed and a new one is allocated.
79
80
81       All  functions  reply  upstream  using qreply(9F). The write-side queue
82       pointer must be provided.
83
84
85       The  dlokack()  function  provides  the   successfull   acknowledgement
86       DL_OK_ACK  message  reply  to the DLPI provider and is used to complete
87       many of the DLPI requests in the DLPI consumer.
88
89
90       The dlerrorack() function provides  the  unsuccessfull  acknowledgement
91       DL_ERROR_ACK message reply to the DLPI() provider and is used for error
92       completions were required for DLPI requests in the DLPI consumer.
93
94
95       The dlbindack() function provides the DL_BIND_ACK message reply to  the
96       DLPI provider and is used to complete the DL_BIND_REQ processing in the
97       DLPI consumer.
98
99
100       The dlphysaddrack() function provides  the  ()DL_PHYS_ADDR_ACK  message
101       reply used to complete the DL_PHYS_ADDR_ACK processing.
102
103
104       The  dluderrorind()  function provides the DL_UDERROR_IND message reply
105       used to complete an unsuccessful DL_UNITDATA_REQ.
106

RETURN VALUES

108       None.
109

NOTES

111       These functions are not required if you are are writing a  DLPI  device
112       driver using gld(7D).
113

CONTEXT

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