AIX Version 4.3 Communications Technical Reference, Volume 1
DL_XID_CON Primitive
Purpose
Conveys an XID data link service data unit (DLSDU) from the data link service (DLS) provider to the DLS user in response to a DL_XID_REQ primitive.
Structure
The primitive consists of one M_PROTO message block, which contains the following structure, followed by zero or more M_DATA blocks containing zero or more bytes of data:
typedef struct
{
ulong dl_primitive;
ulong dl_flag;
ulong dl_dest_addr_length;
ulong dl_dest_addr_offset;
ulong dl_src_addr_length;
ulong dl_src_addr_offset;
} dl_xid_con_t;
Description
The DL_XID_CON conveys an XID DLSDU from the DLS provider to the DLS user in response to a DL_XID_REQ primitive.
Note: This primitive applies to XID and test operations.
Parameters
dl_primitive |
Specifies the DL_XID_CON primitive. |
dl_flag |
Indicates flag values for the request as follows:
DL_POLL_FINAL |
Indicates whether the poll/final bit is set. |
|
dl_dest_addr_length |
Specifies the length of the data link service access point (DLSAP) address of the destination DLS user. If the destination user is implemented using the Data Link Provider Interface (DLPI), this address is the full DLSAP address returned on the DL_BIND_ACK primitive. |
dl_dest_addr_offset |
Indicates where the destination DLSAP address begins. The value of this parameter is the offset from the beginning of the M_PROTO message block. |
dl_src_addr_length |
Specifies the length of the DLSAP address of the source DLS user. |
dl_src_addr_offset |
Indicates where the source DLSAP address begins. The value of this parameter is the offset from the beginning of the M_PROTO message block. |
States
Valid |
The primitive is valid in the DL_IDLE or DL_DATAXFER state. |
New |
The resulting state is unchanged. |
Implementation Specifics
This primitive is part of Base Operating System (BOS) Runtime.
