Function Documentation

LCS_Control* LCS_getControl (  void   )

Return the LCS control handle. Return values: x  LCS control handle NULL  Cannot find handle

LCS_NodeAddress LCS_getNodeAddress (  ITC_NodeID  nid  )

Return the LCB hardware node address for a logical ITC node ID. Parameters: nid  (in) ITC (logical) node ID Return values: LCS_NIH_NONE  LCB (hardware) address not known LCS_NIH_SIU0  LCB (hardware) address for SIU 0 (SC "redundant SIU") LCS_NIH_SIU1  LCB (hardware) address for SIU 1 (SC "primary SIU") LCS_NIH_EPU0  LCB (hardware) address for EPU 0 LCS_NIH_EPU1  LCB (hardware) address for EPU 1 LCS_NIH_EPU2  LCB (hardware) address for EPU 2 LCS_NIH_EPU3  LCB (hardware) address for EPU 3/external SIU LCS_NIH_SDI  LCB (hardware) address for science data interface LCS_getNodeAddress() returns the LCB (hardware) address corresponding to an ITC (logical) node.

ITC_NodeID LCS_getNodeID (  LCS_NodeAddress  nih  )

Return the logical ITC node ID for an LCB hardware node address. Parameters: nih  (in) LCS (hardware) address Return values: ITC_NID_NONE  ITC (logical) node ID not known ITC_NID_SIU  ITC (logical) node ID SIU ITC_NID_EPU0  ITC (logical) node ID EPU 0 ITC_NID_EPU1  ITC (logical) node ID EPU 1 ITC_NID_EPU2  ITC (logical) node ID EPU 2 ITC_NID_EPU3  ITC (logical) node ID EPU 3/external SIU ITC_NID_SSR  ITC (logical) node ID SSR LCS_getNodeID() returns the ITC (logical) node ID corresponding to an LCB (hardware) address.

LRX_Engine* LCS_getRxEngine (  ITC_NodeID  nid, ITC_QueueID  qid )

Return the LRX engine handle. Parameters: nid  (in) ITC node ID qid  (in) ITC queue ID Return values: x  Handle for LRX engine NULL  Cannot find handle LCS_getRxEngine() returns the handle for an LRX engine.

LTX_Engine* LCS_getTxEngine (  ITC_TaskID  tid, ITC_QueueID  qid )

Return the LTX engine handle. Parameters: tid  (in) ITC task ID qid  (in) ITC queue ID Return values: x  Handle for LTX engine NULL  Cannot find handle LCS_getTxEngine() returns the handle for an LTX engine.

unsigned int LCS_setNodeAddressSIU (  LCS_NodeAddress  nih  )

Set the hardware address of the SIU (on EPU only). Parameters: nih  (in) Hardware address of the SIU Return values: LCS_NOTINIT  LCS control block not available LCS_NOTSIUND  Node address is not valid for an SIU LCS_SUCCESS  Success LCS_setNodeAddressSIU() sets up the SIU hardware node address in the LCS mapping tables. Written as a separate routine because the SIU's hardware address cannot be determined until the LCB is initialized. This functionality is only needed on an EPU.

unsigned int LCS_sizeofRxEngine (  void   )

Return size of an LRX engine structure. Return values: x  Size (bytes) of LRX engine

unsigned int LCS_sizeofTxEngine (  void   )

Return size of an LTX engine structure. Return values: x  Size (bytes) of LRX engine
