DLPI Primitives

Connection-mode Service Primitives

maximum allowed number of retries before re-setting the connection. This is sometimes known as the N2 variable.

 

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 primitive is 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_HP_SET_ACK_THRESH_REQ

 

Requests the DLS provider to set the acknowledgment threshold to the

 

specified value.

 

 

Setting the ack thresh will not affect the local window size.

NOTE

 

Format

} dl_hp_set_ack_thresh_req_t;

Parameters dl_primitive

DL_HP_SET_ACK_THRESH_REQ dl_ack_thresh
