函数简介
一次性释放所有通过图片加载函数分配的内存。
接口名称
FreeImageAllDLL调用
int FreeImageAll(long ola);参数说明
| 参数名 | 类型 | 说明 |
|---|---|---|
| ola | 长整数型 | OLAPlug对象的指针,由 CreateCOLAPlugInterFace 接口生成。 |
示例
SDK 调用
cpp
#include "OLAPlugServer.h"
OLAPlugServer ola;
int ret = ola.FreeImageAll();csharp
using OLAPlug;
var ola = new OLAPlugServer();
int ret = ola.FreeImageAll();python
from OLAPlugServer import OLAPlugServer
ola = OLAPlugServer()
ret = ola.FreeImageAll()java
import com.olaplug.OLAPlugServer;
OLAPlugServer ola = new OLAPlugServer();
int ret = ola.FreeImageAll();cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.FreeImageAll()vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.FreeImageAll()text
.局部变量 ola, OLAPlug
ola.创建 ()
ret = ola.FreeImageAll()aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.FreeImageAll();text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.FreeImageAll()cpp
#include "OLAPlugServer.h"
OLAPlugServer ola;
int32_t ret = ola.FreeImageAll();原生 DLL 调用
cpp
long instance = CreateCOLAPlugInterFace();
FreeImageAll(instance);csharp
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 FreeImageAll(long ola);
long instance = CreateCOLAPlugInterFace();
FreeImageAll(instance);python
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.FreeImageAll(instance)返回值
整数型:1 成功,0 失败。
注意事项
- 调用后所有已加载的图片句柄都将失效。
- 如果只需释放特定图片,请使用 FreeImagePtr。
