Interface description4.3.3.7 canSchedulerAddMessageThe function adds a new transmit object to the specified cyclic transmit list. Thecomplete syntax of the function is:HRESULT canSchedulerAddMessage (HANDLEhScheduler,PCANCYCLICTXMSG pMessage,PUINT32 pdwIndex );Parameters:hScheduler[in] Handle of the opened transmit list.pMessage[in] Pointer to an initialized structure of type CANCYCLICTXMSG with thetransmit object.pdwIndex[out] Pointer to a variable of type UINT32. If run successfully, the functionreturns the list index of the newly added transmit object in this variable. Inthe event of an error, the variable is set to the value 0xFFFFFFFF (-1). Thisindex is required for all further function calls.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function vciFormatError.Comments:The cyclic transmit process of the newly added transmit object begins only aftera successful call of the function canSchedulerStartMessage. In addition, thetransmit list must be active (see canSchedulerActivate).4.3.3.8 canSchedulerRemMessageThe function stops processing of a transmit object and removes it from the specifiedcyclic transmit list. The complete syntax of the function is:HRESULT canSchedulerRemMessage (HANDLE hScheduler,UINT32 dwIndex );Parameters:hScheduler[in] Handle of the opened transmit list.74Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
Interface descriptiondwIndex[in] List index of the transmit object to be removed. The list index mustcome from a previous call of the function canSchedulerAddMessage .Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function vciFormatError.Comments:After the function is called, the list index specified in dwIndex is invalid andmust no longer be used.4.3.3.9 canSchedulerStartMessageThe function starts a transmit object of the specified cyclic transmit list. The completesyntax of the function is:HRESULT canSchedulerStartMessage (HANDLE hScheduler,UINT32 dwIndex,UINT16 dwCount );Parameters:hScheduler[in] Handle of the opened transmit list.dwIndex[in] List index of the transmit object to be started. The list index must comefrom a previous call of the function canSchedulerAddMessage .dwCount[in] Number of the cyclic transmit repeats. With the value 0, the transmitprocess is repeated infinitely. The value specified here must be in the range0 to 65535.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function vciFormatError.Comments:The cyclic transmit process only starts if the transmit task is active when thefunction is called. If the transmit task is inactive, the transmit process is delayeduntil the next call of the function canSchedulerActivate.75Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
