Error Injection

The user channel allows the application to send messages with many error types (per message basis).

In order to send an erroneous message, the mxfASCBTxPeriodicUpdateMsgWrite() function may be used. The MXF_ASCB_DATAREC structure contains the control field that specifies the errors to inject.

uint32 rc;
HMXF_CHANNEL user;
HMXF_BUFFER userBufferTx[1];
MXF_ASCB_DATAREC* txBuffer;
MXF_ASCB_DATAREC* txRecAscb;

   ...

   // Override hardware CRC value
   if(!rc)
   {
      txRecAscb = (MXF_ASCB_DATAREC *)txBuffer;
      memset(txRecAscb, 0, sizeof(MXF_ASCB_DATAREC));
      txRecAscb->repeatCount = 1;
      txRecAscb->control = MXF_ASCB_TX_REC_CTRL_HWCRC_NOT_SENT;
      txRecAscb->dataSize = 4;
      txRecAscb->data[0]  = 0x0000;
      txRecAscb->data[1]  = 0x0000;

      rc = mxfASCBTxPeriodicUpdateMsgWrite(userBufferTx[0], 1, txBuffer);
   }
