Specifies the connection-response token assigned to a stream.
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;
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.
| Item | Description |
|---|---|
| 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. |
| Item | Description |
|---|---|
| Valid | The primitive is valid in any state in response to a DL_TOKEN_REQ primitive. |
| New | The resulting state is unchanged. |
