DLPI Primitives
Connection-mode Service Primitives
The message is valid in the states DL_IDLE, DL_DATAXFER,
DL_OUTCON_PENDING, DL_INCON_PENDING,
DL_USER_RESET_PENDING, and DL_PROV_RESET_PENDING.
New State
The resulting state is unchanged.
Response
If the specified dl_ack_thresh is valid and the primitive was issued from a valid state, the DLS provider responds with a DL_OK_ACK. Otherwise a DL_ERROR_ACK is returned.
Reasons for Failure
DL_OUTSTATE
Primitive was issued from an invalid state.
DL_SYSERR
| If the specified dl_ack_thresh is greater than the remote receive | |
| window size, then a DL_ERROR_ACK with dl_errno set to | |
| DL_SYSERR and dl_unix_errno set to EINVAL is returned. | |
| DL_HP_SET_LOCAL_WIN_REQ | |
| Requests the DLS provider to set the local window size to the specified | |
| value. |
|
| Setting the local window size also causes the DLPI read side streams | |
NOTE | ||
| queue hi water mark to be set to (local_window_size * MTU). The | |
| (local_window_size * MTU) cannot exceed (1 << 16) - (2 * MTU). | |
