DLPI Primitives Connection-mode Service Primitives NOTE Setting the ack thresh will not affect the local window size. Format typedef struct { u_long dl_primitive; u_long dl_ack_thresh; } dl_hp_set_ack_thresh_req_t; Parameters dl_primitive DL_HP_SET_ACK_THRESH_REQ dl_ack_thresh maximum number of I PDUs that can be received before an acknowledgment is sent. If this threshold is reached, an acknowledgment is sent and the SEND_ACK timer is restarted. This value cannot be greater than the remote receive window size. State 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 124 Chapter 2
