Service Name <Generic DMx Copy Rx Data> Syntax Buf Req_ Return Type <Generic DMx Copy Rx Data> ( uint8 dm Id, Network Handle Type channel, const Pdu Info Type* info, Pdu Length Type* buffer Size Ptr ) Sync/ Async Synchronous Reentrancy Non Reentrant Parameters (in) dm Id Number of the J1939 diagnostic message. channel Channel on which the message is received. info Provides the source buffer (Sdu Data Ptr) and the number of bytes to be copied (Sdu Length). An Sdu Length of 0 can be used to query the current amount of available buffer in the upper layer module. In this case, the Sdu Data Ptr may be a NULL_ PTR. Param eters (inout) None Parameters (out) buffer Size Ptr Available receive buffer after data has been copied. Return value Buf Req _ - Return - Type BUFREQ_ OK: Data copied successfully BUFREQ_ E_ NOT_ OK: Data was not copied because an error occurred. Descript ion This function is called to provide the received data of a diagnostic message segment to the upper layer. Each call to this function provides the next part of the diagnostic message data. The size of the remaining buffer is written to the position indic ated by buffer Size Ptr. Available via J1939Dcm.h

This function is called to acquire the transmit data of a diagnostic message segment. Each call to this function provides the next part of the diagnostic message data unles s retry - >Tp Data State is TP_ DATARETRY. In this case the function restarts to copy the data beginning at the offset from the current position indicated by retry - >Tx Tp Data Cnt. The size of the remaining data is written to the position indicated by availa ble Data Ptr.

Indicates reception of a Request or Request2 PG for an unsupported diagnostic message.

Called after a diagnostic message has been received, the result indicates whether the reception was successful or not.

This function is called at the start of receiving an diagnostic message.

Called after a diagnostic message has been transmitted, the result indicates whether the transmission was successful or not.

This function resets the J1939 Diagnostic Communication Manager to the uninitialized state.

This function is called to provide the received data of an I - PDU segment (N - PDU) to the upper layer. Each call to this function provides the next part of the I - PDU data. The size of the remaining buffer is written to the position indicated by b uffer Size Ptr.

This function is called t o acquire the transmit data of an I - PDU segment (N - PDU). Each call to this function provides the next part of the I - PDU data unless retry - >Tp Data State is TP_ DATARETRY. In this case the function restarts to copy the data beginning at the offset from the current position indicated by retry - >Tx Tp Data Cnt. The size of the remaining data is written to the position indicated by available Data Ptr.

This function is called at the start of receiving an N - SDU. The N - SDU might be fragmented into multiple N - PDUs (FF with one or more following CFs) or might consist of a single N - PDU (SF). The service shall provide the currently available maximum buffer size when invoked with Tp Sdu Leng th equal to 0.
