Hi,
I have know that signal will interrupt some kind low speed system
call like pipe. But how to design a program that both support signal
and pipe?
I have a mplayer.py to play movie via os.popen2() and mplayer
slave mode. And there is a mplayer_ctl.py send signal to mplayer.py to
trigger function from mplayer.py. Sometimes os.popen2() is reading or
writing when user run mplayer_ctl.py the bad things raise...
Is there some better way to design the programe? Thank you
