[go-nuts] CGO - convert a c.char array to string

[nicolas_boiteux via golang-nuts]

Hello

i have a little problem to convert a C char array to a string array in 
golang.

https://community.bistudio.com/wiki/Extensions

func RVExtensionArgs(output *C.char, outputsize C.size_t, input *C.char, 
argv **C.char, argc C.size_t) {
    temp := fmt.Sprintf("Hello %s %d %s!", C.GoString(input), argc,  C.
GoString(*argv)

    // return to C program, the string
    result := C.CString(temp)
    defer C.free(unsafe.Pointer(result))
    var size = C.strlen(result) + 1
    if size > outputsize {
        size = outputsize
    }
    C.memmove(unsafe.Pointer(output), unsafe.Pointer(result), size)
}

I did this code only to print the content of argv for test purpose. This 
code only return the first string of argv array.

Do you know a standard method to iterate & convert all the argv array in 
one golang string array  ?
