DLPI Primitives

Connectionless-mode Service Primitives

DL_OUTSTATE

Primitive was issued from an invalid state.

DL_UNSUPPORTED

Requested priority not supplied by provider.

DL_UNITDATA_IND

Conveys one DLSDU from the DLS provider to the DLS user.

Format

The message consists of one M_PROTO message block containing the structure shown below, followed by one or more M_DATA blocks containing at least one byte of data. The amount of user data that may be transferred in a single DLSDU is limited. This limit is conveyed by the parameter dl_max_sdu in the DL_INFO_ACK primitive.
