NAME

DL_TEST_RES (dl_test_res_t) - conveys the TEST response DLSDU from the DLS User to the DLS Provider in response to a DL_TEST_IND.

SYNOPSIS

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 {
    t_uscalar_t  dl_primitive;
    t_uscalar_t  dl_flag;
    t_uscalar_t  dl_dest_addr_length;
    t_uscalar_t  dl_dest_addr_offset;
} dl_test_res_t;

PARAMETERS

dl_primitive

conveys DL_TEST_RES

dl_flag

indicates the flag values for the response as follows:

DL_POLL_FINAL

indicates if the poll/final bit is set.

dl_dest_addr_length

conveys the 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

conveys the 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.

NEW STATE

The resulting state is unchanged.

RESPONSE

On an invalid TEST response request, a DL_ERROR_ACK is issued to the usr.

ERRORS

DL_BADADDR

The DLSAP address information was invalid or was in an incorrect format.

DL_BADDATA

The amount of data exceeded the DLS provider's limit for TEST messages.

DL_SYSERR

A System error has occurred and the UNIX System error is indicated in the DL_ERR OR_ACK.

DL_NOTSUPPORTED

DL_OUTSTATE

The primitive was issued from an invalid state

DL_TESTAUTO

Previous bind request specified automatic handling of TEST responses.

DL_UNSUPPORTED
