DLPI Primitives

Connection-mode Service Primitives

size of the local receive window. This value must be greater than 0 and less than 128.

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_local_win 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_local_win is invalid, then a DL_ERROR_ACK with
	dl_errno set to DL_SYSERR and dl_unix_errno set to EINVAL is
	returned.
	DL_HP_SET_REMOTE_WIN_REQ
	Requests the DLS provider to set the remote window size to the speciﬁed
	value.

NOTE	Setting the remote window size causes the ack thresh to be set to
	((remote_window_size + 1) / 2).
