Load a library

If you are loading a 64-bit library in 64-bit Python (or a 32-bit library in 32-bit Python) then you can directly load the library using LoadLibrary.

Important

If you want to load a 32-bit library in 64-bit Python then inter-process communication is used to communicate with the 32-bit library. See Access a 32-bit library in 64-bit Python for more details.

All of the shared libraries in the following examples are included with the MSL-LoadLib package. The C++ and FORTRAN libraries have been compiled in 32- and 64-bit Windows and Linux and in 64-bit macOS. The .NET library was complied in 32- and 64-bit using Microsoft Visual Studio 2017. The kernel32 library is a 32-bit library and it is only valid on Windows (since it uses the __stdcall calling convention). The LabVIEW library was built using 32- and 64-bit LabVIEW on Windows. The Java libraries are platform and bitness independent since they run in the JVM.

Tip

If the file extension is not specified then a default extension, .dll (Windows), .so (Linux) or .dylib (macOS) is used.
