Primitives to Handle XID and TEST Operations

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.
New State
The resulting state is unchanged.
DL_XID_REQ
Conveys one XID DLSDU from the DLS user to the DLS provider for
transmission to a peer DLS user.
Format
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;
}
dl_xid_req_t;
Parameters
dl_primitive
