标 题: how can python code wait for signal from a c code program ?
发信站: BBS 未名空间站 (Mon Jul 29 21:30:13 2013, 美东)
hi we have a program from c code, it uses named pipe,
then use select() to wait on it,
basically if someone writes data into this pipe,
we'll catch it with select() (not 100% sure, but sth. like this)
normally another c code process can catch this and reports we get data.
i want to replace it with python, how can i do that ?
i mean how can i wait for this write-to-pipe signal ?
many thanks !h | r****t

other processes to write.
