You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: input.go
    path of file: ./repos/darktile/vendor/github.com/go-gl/glfw/v3.3/glfw
    
    the code of the file until where you have to start completion: package glfw

//#include <stdlib.h>
//#define GLFW_INCLUDE_NONE
//#include "glfw/include/GLFW/glfw3.h"
//void glfwSetJoystickCallbackCB();
//void glfwSetKeyCallbackCB(GLFWwindow *window);
//void glfwSetCharCallbackCB(GLFWwindow *window);
//void glfwSetCharModsCallbackCB(GLFWwindow *window);
//void glfwSetMouseButtonCallbackCB(GLFWwindow *window);
//void glfwSetCursorPosCallbackCB(GLFWwindow *window);
//void glfwSetCursorEnterCallbackCB(GLFWwindow *window);
//void glfwSetScrollCallbackCB(GLFWwindow *window);
//void glfwSetDropCallbackCB(GLFWwindow *window);
//float GetAxisAtIndex(float *axis, int i);
//unsigned char GetButtonsAtIndex(unsigned char *buttons, int i);
//float GetGamepadAxis
    
func goDropCB(window unsafe.Pointer, count C.int, names **C.char) { // TODO: The types of name can be `**C.char` or `unsafe.Pointer`, use whichever is better.
	w := windows.get((*C.GLFWwindow)(window))
	namesSlice := make([]string, int(count)) // TODO: Make this better. This part is unfinished, hacky, probably not correct, and not idiomatic.
	for i := 0; i < int(count); i++ {        // TODO: Make this better. It should be cleaned up and vetted.
		var x *C.char                                                                                 // TODO: Make this better.
		p := (**C.char)(unsafe.Pointer(uintptr(unsafe.Pointer(names)) + uintptr(i)*unsafe.Sizeof(x))) // TODO: Make this better.
		namesSlice[i] = C.GoString(*p)                                                                // TODO: Make this better.
	}
	w.fDropHolder(w, namesSlice)
