Hello,
Could you guys please help me.
I can't find how to export method function which belongs to some go-struct
to C-code (cgo part) as callback. I know how to export simple function
which not belongs to any type and use it as callback for C-function, but is
it possibly to export method of concrete struct instance? since I need
additional info when callback will be called from C-code. As example what
I'm trying to explain:
// extern int goCallbackHandler(int, int);//// static int doAdd(int a, int b)
{// return goCallbackHandler(a, b);// }
import "C"
type A struct {
... some data which used to process callback from C-side
}
// export cgo_callback
func (a *A) cgo_callback(...){ <-----main problem here
}
main {
C.doAdd(...)
}
I can't modify c-side - I have only compiled library, so I don't know how
to identify which instance of struct should be used to properly process
C-call of go-side callback.
Thanks,
Andrey
