C/C++ Libraries • 535.23 _7200_GetOverrunStatus@ DescriptionWhen using _7200_DI_DMA_Start to convert Digital I/O data with doublebuffer mode enabled, and not using _7200_DblBufferTransfer to moveconverted data then double buffer overrun will occur. Use this function tocheck overrun count.@ SyntaxVisual C++ (Windows 95)int W_7200_GetOverrunStatus (U32 * overrunCount)Visual Basic (Windows 95)int W_7200_GetOverrunStatus (overrunCount As Long) As LongC/C++ (DOS)int _7200_GetOverrunStatus (U32 *overrunCount )@ ArgumentoverrunCount: number of overruns.@ Return CodeERR_NoError5.24 _7200_DO_DMA_Start@ DescriptionThe function will perform digital output N times with DMA data transfer byusing the following four sampling modes:1. Pacer trigger (internal timer trigger, TIME 1)2. Internal timer pacer with O_REQ enabled3. O_REQ & O_ACK handshakingIt takes place in the background which will not be stop until the Nthconversion has been completed or the program executes the_7200_DO_DMA_Stop function to stop the process. After executing thisfunction, it is necessary to check the status of the operation by using thefunction _7200_DO_DMA_Status.@ SyntaxVisual C++ (Windows 95)int W_7200_DO_DMA_Start (U8 mode, U32 count, U32 handle,Boolean repeat)Visual Basic (Windows 95)W_7200_DO_DMA_Start (ByVal mode As Byte, ByVal count As Long,ByVal handle As Long, ByVal repeat as Byte) As Long
