hi
don't success to solve this subject. Here an example with the simple code
shown in those slides:
http://akrennmair.github.io/golang-cgo-slides/#10
This code doesn't works anymore, or perhaps there is some special command
line to build it ?
I thought it was possible to create a C function

i have some news.
With this kind of declaration
extern void __fastcall RVExtension(char *output, int outputSize, const char
*function){
goRVExtension(output, outputSize, function);
};
// export goRVExtension
func goRVExtension(output *C.char, outputsize C.size_t, input *C.char) {

as asked by Jason, i give more information.
I build a 32 bits .dll and there was no error message. When i launch the
dll with the c program, the c program return a generic error message
"method is not recognized" wich happens when the entry point name is wrong.
So the C program expected a
the dll is build but the entry point not works correctly :(

Hello,
I need some assistance to export a GO dll function to a C program.
The C program (wich i m not the author) required to call a function with
this name: _RVExtension@12
so, i simply declare my go function like this:
//export _RVExtension@12
func _RVExtension@12(output *C.char, outputsize
i finaly have it :D in fact, the whole struct of httpbin returns have to be
describe through different structures to works.
package main
import (
"bytes"
"encoding/json"
"fmt"
"net/http"
)
func main() {
type User struct {
Firstname string `json:"firstname"`
and without the use of http.post, the encode / decode methods works :(
i also try this but it doesn't work too.
func main() {
type User struct {
Firstname string `json: "firstname"`
Lastname string `json: "lastname"`
}
type httpbin struct {
Origin string
when i try something like that:
res, _ := http.Post("https://httpbin.org/post;, "application/json;
charset=utf-8", b)
var newuser map[string]interface{}
json.NewDecoder(res.Body).Decode()
fmt.Println(newuser["json"])
it prints me correctly the content a map containing the ID &
i try to parse the return of httpbin :)

i don't find any information about this problem :( it doesnt seems to be
relative to c.cstring cause when i use a simple string "hello" instead of
the data return the dll crash too.
if i use the same code in .exe it works fine.

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!",
Do you mean we can for example build a GO .dll wich declare an entry point
usable by C/C++ game ?
I can give it a try easily with ARMA game wich load those kind of extension.
