函数简介

释放指定的内存。

接口名称

VirtualFreeEx

DLL调用

int VirtualFreeEx(long instance, long hwnd, long addr);

参数说明

参数名	类型	说明
instance	长整数型	OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
hwnd	长整数型	窗口句柄或进程ID。
addr	长整数型	要释放的内存地址。

示例

SDK 调用

#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.VirtualFreeEx(hwnd, 0);

using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.VirtualFreeEx(hwnd, 0);

from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.VirtualFreeEx(hwnd, 0)

import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.VirtualFreeEx(hwnd, 0);

var ola = com("OlaPlug.OlaSoft")
var ret = ola.VirtualFreeEx(hwnd, 0)

Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.VirtualFreeEx(hwnd, 0)

.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.VirtualFreeEx(hwnd, 0)

import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.VirtualFreeEx(hwnd, 0);

变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.VirtualFreeEx(hwnd, 0)

#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.VirtualFreeEx(hwnd, 0);

原生 DLL 调用

long instance = CreateCOLAPlugInterFace();
VirtualFreeEx(instance, hwnd, 0);

using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int VirtualFreeEx(long ola, long hwnd, long addr);

long instance = CreateCOLAPlugInterFace();
VirtualFreeEx(instance, hwnd, 0);

from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ola.VirtualFreeEx(instance, hwnd, 0)
