there are two IPC messages, both sent to your ml plugins messageproc. Get the message IDs by doing:
ML_IPC_MENUFUCKER_BUILD = SendMessage(plugin.hwndWinampParent, WM_WA_IPC, (WPARAM)&"menufucker_build", IPC_REGISTER_WINAMP_IPCMESSAGE);
ML_IPC_MENUFUCKER_RESULT = SendMessage(plugin.hwndWinampParent, WM_WA_IPC, (WPARAM)&"menufucker_result", IPC_REGISTER_WINAMP_IPCMESSAGE);

ML_IPC_MENUFUCKER_BUILD:
This is sent just before the menu is shown. param1 is a pointer to a menufucker_t struct.
Do what you like to the menu, if you add anything, give it the id nextidx, and increment nextidx

ML_IPC_MENUFUCKER_RESULT:
param1 is a pointer to a menufucker_t struct, param2 is the id of the menu item selected
