You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: process_windows_64bit.go
    path of file: ./repos/podman/vendor/github.com/shirou/gopsutil/v3/process
    
    the code of the file until where you have to start completion: //go:build (windows && amd64) || (windows && arm64)
// +build windows,amd64 windows,arm64

package process

import (
	"syscall"
	"unsafe"

	"github.com/shirou/gopsutil/v3/internal/common"
	"golang.org/x/sys/windows"
)

type PROCESS_MEMORY_COUNTERS struct {
	CB                         uint32
    
func readProcessMemory(procHandle syscall.Handle, _ bool, address uint64, size uint) []byte {
	var read uint

	buffer := make([]byte, size)

	ret, _, _ := common.ProcNtReadVirtualMemory.Call(
		uintptr(procHandle),
		uintptr(address),
		uintptr(unsafe.Pointer(&buffer[0])),
		uintptr(size),
		uintptr(unsafe.Pointer(&read)),
	)
	if int(ret) >= 0 && read > 0 {
		return buffer[:read]
	}
	return nil
}
