谁能告诉我我做错了什么?我正在尝试在不同的线程上运行自定义主线程。
这是代码。
.exe
主要.cpp
#include "dll_class.h"
#include <iostream>
int main(void);
DllClass object(main);
int main(void)
{
std::cout << "Enter the main code.\n";
std::getchar();
}
.dll
dll_class.h
#include "platform.h"
#include <iostream>
class DLL_API DllClass //DLL_API is just a macro for import and export.
{
public:
DllClass(int(*main)(void))
{
std::cout << "Start application.\n";
platform = new Platform(main);
}
~DllClass(void)
{
delete platform;
}
private:
Platform* platform;
};
平台.h
class DLL_API Platform
{
public:
Platform(main_t main_tp);
~Platform(void){}
};
平台.cpp
#include "platform.h"
#include "Windows.h"
#include <iostream>
HHOOK hookHandle;
int(*main_p)(void);//This will hold a the main function of the the .exe.
LRESULT CALLBACK keyHandler(int nCode, WPARAM wParam, LPARAM lParam);
DWORD WINAPI callMain(_In_ LPVOID lpParameter)
{
std::cout << "Calling the main function.\n";
main_p();
return 0;
}
Platform::Platform(int(*main_tp)(void))
{
main_p = main_tp;
CreateThread(NULL, 0, callMain, NULL, 0, NULL);
std::cout << "Setting hooks.\n";
hookHandle = SetWindowsHookEx(WH_MOUSE_LL, keyHandler, NULL, 0);
std::cout << "Enter message loop.\n";
MSG message;
while(GetMessage(&message, (HWND)-1, 0, 0) != 0){
TranslateMessage( &message );
DispatchMessage( &message );
}
}
LRESULT CALLBACK keyHandler(int nCode, WPARAM wParam, LPARAM lParam)
{
std::cout << "Inside the hook function.\n" << std::endl;
return CallNextHookEx(hookHandle, nCode, wParam, lParam);
}
它运行得很好,直到某个时刻。这是输出。
Start application.
Setting hooks.
Calling the main function.
Enter message loop.
Inside the hook function. (A lot of times of course).
但它从来没有说:
Enter the main code.
难道不能让dll调用exe函数吗?
