DLPI Primitives

Primitives to Handle XID and TEST Operations

The message consists of one M_PROTO message block, followed by zero or more M_DATA blocks containing zero or more bytes of data. The message structure is as follows:

typedef struct	{
ulong	dl_primitive;
ulong	dl_flag;
ulong	dl_dest_addr_length;
ulong	dl_dest_addr_offset;
ulong	dl_src_addr_length;
ulong	dl_src_addr_offset;

}dl_xid_ind_t;

Parameters

dl_primitive

DL_XID_IND

dl_ﬂag

ﬂag values associated with the received XID frame:

DL_POLL_FINAL indicates if the received xid frame had the poll/ﬁnal bit set.

dl_dest_addr_length

length of the DLSAP address of the destination DLS user. If the destination user is implemented using DLPI, this address is the full DLSAP address returned on the DL_BIND_ACK.

dl_dest_addr_offset

offset from the beginning of the M_PROTO message block where the destination DLSAP address begins.

dl_src_addr_length

length of the source DLSAP address. If the source user is implemented using DLPI, this address is the full DLSAP address returned on the DL_BIND_ACK.

dl_src_addr_offset

offset from the beginning of the M_PROTO message block where the source DLSAP address begins.

State

The message is valid in states DL_IDLE and DL_DATAXFER.
