linux - Signal generated for closing the window? -

-

i'm using centos 6.3(final) version. question signal generated on pressing close button window? close button equivalent alt-f4? or whole understanding wrong , centos not use signal model it's graphical windows?

if possible please specify source of answer since need document it.

thanks

assuming talking @ x11 level here signal looking wm_delete_window or destroyrequest/destroynotify event.

this has nothing (again @ x11 level) signal(2) or signal(7). though entirely possible in circumstances (hung processes or similar) signals used terminate terminal process.

it shell/etc. running inside terminal going receive various signals terminate operation.
