Here is the gist for showing how to send string from c to go without a copy, for sending an float32 array from c to go without copy, please see here

Below is the documentation for converting between a c string and a go string:

// From https://golang.org/cmd/cgo/
// A few special functions convert between Go and C types by making copies of the data. 
// Go string to C string
// The C string is allocated in the C heap using malloc.
// It is the caller's responsibility to arrange for it to be
// freed, such as by calling C.free (be sure to include stdlib.h

Mounting the shared path You can mount the shared folder using

mount -t 9p -o trans=virtio [mount tag] [mount point] -oversion=9p2000.L

mount tag: As specified in Qemu commandline. mount point: Path to mount point. trans: Transport method (here virtio for using 9P over virtio) version: Protocol version. By default it is 9p2000.u . Other options that can be used include:

package main

import (
	"fmt"
	"unsafe"
)

func byteSliceToFloat32Slice(src []byte) []float32 {
	if len(src) == 0 {
		return nil

go code (foo.go) compiled into a shared library and a c header (foo.h) is generated.

For calling go from c, please see here

Arguments

The code below shows two ways of passing string parameter to go function:

1. Using GoString structure as argument, without making a copy in go code: no conversion to go string needed.
2. Using c_char_p as argument, making a copy in go code when converting to go string.

When using the first method without the copy, I don't know how python will do the memory management with the pointer passed into go. So the second method is preferred.
