DLPI Primitives
Primitives to Handle XID and TEST Operations
The resulting state is unchanged.
Response
The DLS user must respond with a DL_TEST_RES.
DL_TEST_RES
Conveys the TEST response DLSDU from the DLS user to the DLS provider in response to a DL_TEST_IND.
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_test_res_t;
Parameters
dl_primitive
DL_TEST_RES
dl_flag
flag values for the response as follows:
DL_POLL_FINAL indicates if the poll/final bit is 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.
State
The message is valid in states DL_IDLE and DL_DATAXFER.
