VCI - Virtual CAN Interface - Ixxat

Interface description4.3.3 Cyclic transmit listWith the transmit list, up to 16 different CAN message objects can be transmittedcyclically. These interfaces provides functions to configure, start and stop the cyclictransmit messages.4.3.3.1 canSchedulerOpenThe function opens the cyclic transmit list of a CAN connection on a CAN interfaceboard. The complete syntax of the function is:HRESULT canSchedulerOpen(HANDLE hDevice,UINT32 dwCanNo,PHANDLE phScheduler )Parameters:hDevice[in] Handle of the CAN interface board.dwCanNo[in] Number of the CAN connection of the transmit list to be opened. Thevalue 0 selects the first connection, the value 1 the second connection andso on.phScheduler[out] Pointer to a variable of type HANDLE. If run successfully, the functionreturns the handle of the opened transmit list in this variable. In the eventof an error, the variable is set to ZERO.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:If the value 0xFFFFFFFF is specified in the parameter dwCanNo, the functiondisplays a dialog window to select a CAN interface board and a CAN connectionon the screen. In this case the function expects the handle of a higher orderwindow, or the value ZERO if no higher order window is available, in theparameter hDevice and not the handle of the CAN interface board.70Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
