[go-nuts] How to return a Go struct to C

[Song Liu]

Hi,

I have a shared lib as bellow:

/*

#include <stdint.h>


struct Media {

    char*    Name;

    char*    Path;

    uint64_t Size;

};

*/

import "C"


//export GetMediaFromDB


func GetMediaFromDB(filename *C.char) *C.struct_Media {


    c_struct_media := &C.struct_Media{}


    return c_struct_media

}


Which is called in another program written by C, but when it's running it 
report error:

panic: runtime error: cgo result has Go pointer

Could you help with the correct way to return a struct from Go ?

Many thanks.

Thanks,
Song
