Count variable - ibcntl
The variable ibcntl is updated with the number of bytes transmitted on every read and write function call.
Overview of Interface Functions
The library functions are adapted to the interface functions of National Instruments for GPIB
programming. The functions supported by the libraries are listed in the following table.
Function Description
RSDLLibfind() Provides a handle for access to a device.
RSDLLibwrt() Sends a zero-terminated string to a device.
RSDLLilwrt() Sends a certain number of bytes to a device.
RSDLLibwrtf() Sends the contents of a file to a device.
RSDLLibrd() Reads data from a device into a string.
RSDLLilrd() Reads a certain number of bytes from a device.
RSDLLibrdf() Reads data from a device into a file.
RSDLLibtmo() Sets timeout for RSIB functions
RSDLLibsre() Switches a device into the local or remote state
RSDLLibloc() Temporarily switches a device into the local state
RSDLLibeot() Enables/disables the END message for write operations.
RSDLLibrsp() Performs a serial poll and provides the status byte.
RSDLLibclr Sends the command SDC (Device Clear) to the instrument.
RSDLLibonl() Sets the device On/Offlline.
RSDLLTestSrq() Checks whether a device has generated an SRQ.
RSDLLWaitSrq() Waits until a device generates an SRQ.
RSDLLSwapBytes Swaps the byte sequence for binary numeric display (only required for non-Intel platforms)
