Function Documentation

FORK_cb_status LTX_resultList (  FORK_cb_prm *  prm, FORK_msg_hdr *  msg )  [static]

Process a result list posted back by the LCB. Parameters: prm  (in) User context parameter msg  (in) Fork message Return values: FORK_C_CONTINUE  Continue fork ~FORK_C_CONTINUE  Shut down fork LTX_resultList() processes LCB result lists posted back to LTX. Processing involves synchronizing multiple messages if so requested (only allocation requests and last packet sends currently request synchronization) then executing the next processing step defined in the synchronization mechanism.

Here is the call graph for this function:

unsigned int LTX_sendFirst (  LTX_Engine *  txe  )

LTX service task send first packet. Parameters: txe  (in) Transmit engine Return values: x  Assorted

Here is the call graph for this function:

FORK_cb_status LTX_sendNext (  LTX_Engine *  txe, unsigned int  status )

Field the result item resulting from an event message send. Parameters: txe  (in) Transmit engine status  (in) Status from previous packet Return values: FORK_C_CONTINUE  Continue fork ~FORK_C_CONTINUE  Shut down fork

Here is the call graph for this function:

unsigned int LTX_service (  void *  prm, const ITC_QueueItem *  qitem, void *  qipay, unsigned int  qilen )

LTX service task queue item callback routine. Parameters: prm  (in) User context parameter qitem  (in) Queue item qipay  (in) Queue item payload pointer qilen  (in) Queue item payload length Return values: x  Assorted

Here is the call graph for this function:

unsigned int LTX_submit (  LTX_Engine *  txe, LCBD_cl_event *  cl, unsigned int  siz )

Construct an LTX packet (all kinds) and submit to the LCB. Parameters: txe  (in) LTX transmit engine cl  (in) LCB command list siz  (in) Size of buffer to send (note 1) Note: This is an uncorrected byte count (no "cell rounding") for the packet payload. This routine will deal with adding any necessary header words, cell rounding, and converting to the eight-byte count required by the command list description. Return values: LCS_LCBBIND  LCB bind failed LCS_LCBSUBMT  LCB submit failed LCS_SUCCESS  Success
