汇编转机器码 - Assemble ​

函数简介 ​

将汇编语言字符串转换为机器码，以16进制字符串形式输出。

接口名称 ​

Assemble

DLL调用 ​

long Assemble(long instance, string asmStr, long baseAddr, int arch, int mode);

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。
asmStr字符串汇编语言字符串，大小写均可，如"mov eax,1"。
baseAddr长整数型汇编指令所在的地址，用于计算相对地址。
arch整数型架构类型：
0: x86
1: arm
2: arm64。
mode整数型模式：
16: 16位
32: 32位
64: 64位。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string result = ola.Assemble("mov eax,1", 0, 0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string result = ola.Assemble("mov eax,1", 0, 0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
result = ola.Assemble("mov eax,1", 0, 0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
String result = ola.Assemble("mov eax,1", 0, 0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
var result = ola.Assemble("mov eax,1", 0, 0, 0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
result = ola.Assemble("mov eax,1", 0, 0, 0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
result ＝ ola.Assemble(“mov eax,1”, 0, 0, 0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var result = ola.Assemble("mov eax,1", 0, 0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
文本型 result = ola.Assemble("mov eax,1", 0, 0, 0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string result = ola.Assemble("mov eax,1", 0, 0, 0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long ptr = Assemble(instance, "mov eax,1", 0, 0, 0);
if (ptr != 0) {
    char buffer[512] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
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 GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long Assemble(long ola, string asmStr, long baseAddr, int arch, int mode);

long instance = CreateCOLAPlugInterFace();
long ptr = Assemble(instance, "mov eax,1", 0, 0, 0);
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string result = sb.ToString();
}
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()
ptr = ola.Assemble(instance, "mov eax,1", 0, 0, 0)
if ptr:
    buf = create_string_buffer(512)
    ola.GetStringFromPtr(ptr, buf, 512)
    ola.FreeStringPtr(ptr)
    result = buf.value.decode("utf-8")

返回值 ​

返回值说明
（返回值）长整数型，成功返回机器码字符串的指针，失败返回0。返回的字符串指针需要调用 FreeStringPtr 释放内存。

注意事项 ​

项目说明
释放内存返回的字符串指针需要调用 FreeStringPtr 释放内存。
baseAddr参数用于计算相对地址baseAddr参数用于计算相对地址，对于绝对地址指令可以设为0。
不同架构和模式支持的指令集不同不同架构和模式支持的指令集不同。
机器码机器码输出格式为16进制字符串，如"aa bb cc"。
