Gaim Plugin Request

Yeah, found it. Thanks, had to prove a point.

Could you guys not go off topic........... I just want to know is
A) is it doable with reasonable amount of work?
B) If anyone is willing to do it?

A) is it doable with reasonable amount of work?

Yes.  A lot of work, but not unreasonable. 

B) If anyone is willing to do it?

Probably not.  People around here don't seem to care about Windows. 

If anybody is interested, however, I might be able to get some information on how to compile Gaim plugins for Windows.  I don't want to bug the guy, but I will if somebody here wants me to find out.

Probably not.  People around here don't seem to care about Windows. 

And yet the majority of "people" use Windows!

I'm going to laugh when I end up being the one who writes this. -sigh-

[Towelie]

start now!

I might be interested in writing this, please contact me with any information you can get.

You won't finish it.

[Joe]

Sure I will. It'll be a leached combo of yPlugin and iago's encoding thing. =)

I'm guessing that what you need is to install cygwin, go into the "plugins" directory, make your plugin called <pluginname>.c, then compile it by doing "make <pluginname>.dll

[rabbit]

Or you could use MinGW and do "gcc -c -DBUILD_DLL winamp_plugin.c; gcc -shared -o winamp_plugin.dll -Wl,--out-implib,libwinamp_plugin.a winamp_plugin.o"

char *GetWinampSongTitle(HWND Winamp, DWORD Index) // Winamp 2.04+, pointer is in local address space {
   static char SongTitle[1024];

   DWORD WinampProcessID;
   HANDLE WinampProcess;
   char *SongTitleRemote;
   char *Ret = NULL; // Return value

   GetWindowThreadProcessId(Winamp, &WinampProcessID); // get pid

   if(WinampProcess = OpenProcess(PROCESS_VM_READ, FALSE, WinampProcessID)) { // open process
      if(SongTitleRemote = GetWinampSongTitleRemote(Winamp, Index)) { // get pointer
         if(ReadProcessMemory(WinampProcess, SongTitleRemote, SongTitle, sizeof(SongTitle), NULL)) { // read it
            Ret = SongTitle; // success
         }
      }
      CloseHandle(WinampProcess);
   }

   return Ret;
}

From yPlugin2.

[Newby]

From yPlugin2.

Now all you have to do is stick that in a plugin, make all the appropriate hooks / calls, compile it, and release it, and you'll be done!

[iago]

Or you could use MinGW and do "gcc -c -DBUILD_DLL winamp_plugin.c; gcc -shared -o winamp_plugin.dll -Wl,--out-implib,libwinamp_plugin.a winamp_plugin.o"

Don't forget, you have to add Gaim's libraries and include files.  That's why make is handy.
