.TH DL_BIND_ACK 7 "2004/01/12 23:45:10" "LiS-2_16_18-8" "Linux STREAMS"
.SH NAME
.B DL_BIND_ACK (dl_bind_ack_t)
\- reports the successful bind of a DLSAP to a stream, and returns the bound
DLSAP address to the DLS user.  This primitive is generated in response to a
.BR DL_BIND_REQ (7).
.SH SYNOPSIS
The message consists of one
.B M_PCPROTO
message block, which contains the following structure:
.sp
.nf
\fC\s-1\
typedef struct {
    t_uscalar_t  dl_primitive;
    t_uscalar_t  dl_sap;
    t_uscalar_t  dl_addr_length;
    t_uscalar_t  dl_addr_offset;
    t_uscalar_t  dl_max_conind;
    t_uscalar_t  dl_xidtest_flg;
} dl_bind_ack_t;
\fR\s+1
.fi
.SH PARAMETERS
.TP 16
.I dl_primitive
conveys
.BR DL_BIND_ACK .
.TP
.I dl_sap
conveys the DLSAP address information associated with the bound DLSAP.  It
corresponds to the dl_sap field of the associated
.BR DL_BIND_REQ (7),
which contains either part or all of the DLSAP address.  For that portion of
the DLSAP address conveyed in the
.BR DL_BIND_REQ (7),
this field contains the corresponding portion of the address for the DLSAP
that was actually bound.
.TP
.I dl_addr_length
conveys the length of the complete DLSAP address that was bound to the DLPI
stream (see
.BR dlpi (7)
for a description of DLSAP addresses).  The bound DLSAP is chosen according to
the guidelines presented under the description of
.BR DL_BIND_REQ (7).
.TP
.I dl_addr_offset
conveys the offset from the beginning of the
.B M_PCPROTO
block where the DLSAP address begins.
.TP
.I dl_max_conind
conveys the allowed, maximum number of outstanding
.BR DL_CONNECT_IND (7)
messages to be supported on the DLPI stream.  If the value is zero, the stream
cannot accept any
.BR DL_CONNECT_IND (7)
messages.  If greater than zero, the DLS user will accept
.BR DL_CONNECT_IND (7)
messages up to the given value before having to respond with a
.BR DL_CONNECT_RES (7)
or a
.BR DL_DISCONNECT_REQ (7).
The rules for negotiating this value are presented under the description of
.BR DL_BIND_REQ (7).
.TP
.I dl_xidtest_flg
conveys the XID and TEST responses supported by the provider.
.RS
.TP
.B DL_AUTO_XID
XID response handled automatically
.TP
.B DL_AUTO_TEST
TEST response handled automatically.
.PP
If no value is specified in
.IR dl_xidtest_flg ,
it indicates that automatic handling of XID and TEST responses is not
supported by the Provider.
.RE
.SH STATE
The message is valid in state
.BR DL_BIND_PENDING .
.SH "NEW STATE"
The resulting state is
.BR DL_IDLE .
