This could be very useful for a project I am just starting on. No documentation, and example has no content makes the learning curve a bit steep. Does anyone

  The example seems straightforward: Include this package, and your usual os calls start going through their "fakecgo" path.

  It’s pretty simple to use if you are familiar with dlopen and friends. Just call purego.Dlopen(“libname.so”, purego.RTLD_GLOBAL) Take the returned library (make sure to check for errors with purego.Dlerror() first) and call purego.Dlsym(lib, “cfuncName”). If it exists than u can call it with either purego.SyscallN or purego.RegisterFunc

    It would be good to have more documentation on usage, though; things like how to deal with struct padding (or packed structs), common OS API types (presumably manual munging of UCS2/UTF16 is needed for Windows), etc; at least to mention that it's unchanged from …/x/sys? It's easier with dlopen because it's still C and therefore you have the normal headers…

    +1 for additional examples or documentation. Particularly an example that takes a c struct pointer would be awesome. What happens to const char* return values that are null ? I think it is empty string, but either test case or doc confirming it would be awesome
