     t_uscalar_t addrlen, t_uscalar_t maxconind,  t_uscalar_t xidtest);

     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 formulating 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.
