CGO: void* pointer handling

Getting Help
1

I have C struct like that:

typedef struct {
void* data;
} foo;

I want to use CGO to copy it to equivalent go struct

type foo struct {
data unsafe.Pointer
}

but I get panic: runtime error: cgo argument has Go pointer to unpinned Go pointer
what should I do?

2

also, when I try to pin the data using runtime.Pinner it complains that data IS NOT go pointer…

3

How are you setting the data field before you pass it to C?

Ok, bug in pinner will be fixed in next go release
