示例

SDK 调用

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.GetStringSize(0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.GetStringSize(0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.GetStringSize(0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.GetStringSize(0);
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.GetStringSize(0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.GetStringSize(0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret = ola.GetStringSize(0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.GetStringSize(0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.GetStringSize(0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.GetStringSize(0);

原生 DLL 调用

cpp
GetStringSize(instance, 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);

GetStringSize(instance, 0);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

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

返回值

返回值说明
(返回值)整型数:字符串缓冲区大小。

注意事项

项目说明
大小不包含终止符 '\0'返回的大小不包含终止符 '\0',分配缓冲区时需要 +1。
