Migrate from InstrumentDLL

Major differences

Error reporting

Most Instrument DLL functions return an error code, in LibTiePie an internal status flag is set, indicating how the function was executed. Use LibGetLastStatus for testing if the last function was executed succesfully.

Open instrument (InitInstrument)

LibTiePie supports the use of multiple and/or combined instruments using the same library. To use an instrument it is required to open an handle to the instrument. Please read the using LibTiePie and device list sections.
