AIX Version 4.3 Communications Technical Reference, Volume 1
DL_TOKEN_ACK Primitive
Purpose
Specifies the connection-response token assigned to a stream.
Structure
The primitive consists of one M_PCPROTO message block, which contains the following structure:
typedef struct
{
ulong dl_primitive;
ulong dl_token;
} dl_token_req_t;
Description
The DL_TOKEN_ACK primitive is sent in response to the DL_TOKEN_REQ primitive. The DL_TOKEN_ACK primitive specifies the connection-response token assigned to the stream.
Note: This primitive applies to connection mode.
Parameters
dl_primitive |
Specifies the DL_TOKEN_ACK primitive. |
dl_token |
Specifies the connection-response token associated with a stream. This value must be a nonzero value. After an initial DL_TOKEN_REQ primitive is issued on a stream, the data link service (DLS) provider generates the same token value for each subsequent DL_TOKEN_REQ primitive issued on the stream.
The DLS provider generates a token value for each stream upon receipt of the first DL_TOKEN_REQ primitive issued on that stream. The same token value is returned in response to all subsequent DL_TOKEN_REQ primitives issued on a stream. |
States
Valid |
The primitive is valid in any state in response to a DL_TOKEN_REQ primitive. |
New |
The resulting state is unchanged. |
Implementation Specifics
This primitive is part of Base Operating System (BOS) Runtime.
