Starting from the Go side, lets say the function you want to use has a signature like this: func TheFunc(in []string) []string You could just export this in your shared library, which would give a C signature of: extern GoSlice TheFunc(GoSlice p0); WebGoSlice already provides several basic modifiers. Generator handler.GCodeGenerator The generator then generates the final gcode based on the data the modifiers added. The …
WebYou could convert each string in your slice to a null-terminated string. And assemble them in a slice of type "* C.char". Then you can pass a pointer to the first element of that slice. It will be of type "** C.char". In your GetWork C function it would be declared as "char **string_list". I've probably not explained that very well. Web1. To start, C doesn't know about the Go slice type, nor how to manipulate it, so you should return an array pointer just like you would in C. You also can't allocate the slice in Go …
