[英]IDA pro 'this' keyword
I am wondering what the exact meaning of the 'this' keyword is in the IDA pro pseudo c++ code. 我想知道'this'关键字在IDA pro伪c ++代码中的确切含义是什么。
Lets say that I have a function call: 让我们说我有一个函数调用:
v2 = sub_100010B3((int)&v12, "QtGui4.dll");
Which call this function: 哪个叫这个功能:
int __thiscall sub_100010B3(int this, const char *Str1)
{
int result; // eax@2
int v3; // eax@4
int v4; // [sp+0h] [bp-8h]@1
int v5; // [sp+4h] [bp-4h]@1
v4 = this;
v5 = sub_10001090(this, 1);
if ( v5 )
{
while ( *(_DWORD *)(v5 + 16) )
{
v3 = sub_10001470(v4, *(_DWORD *)(v5 + 12));
if ( !stricmp(Str1, (const char *)v3) )
return v5;
v5 += 20;
}
result = 0;
}
else
{
result = 0;
}
return result;
}
Ok, so in the function we can see the definition 'int this' which according to the docs is a pointer to the object which is used to invoke the object. 好的,所以在函数中我们可以看到定义'int this',根据docs是一个指向用于调用对象的对象的指针。 What I am wondering is how I can rewrite the function so that they will operate the same but do not need to pass the 'this' parameter?
我想知道的是我如何重写函数以便它们将运行相同但不需要传递'this'参数?
The thiscall means it is a Class member function so you would want to rewrite it as thiscall表示它是一个Class成员函数,因此您需要将其重写为
class MyClass {
int sub_100010B3(const char* Str1);
};
MyClass::sub_100010B3(const char* Str1)
{
// .. implementation
}
