Re: A portable code question
Or if you want this behaviour all the time, one call of
setvbuf(mypipe,(char *)0,_IONBF,0);
should do the trick (much easier than remebering to have to call fflush()
all the time).
If not using streams, and just calling write(), then you probably don't have
to worry.

BTW, "system('sleep 1');" probably won't compile, and 'system("sleep 1");'
is bad news. Try "man 3 sleep" for more info.

Assuming you're using file streams to write to the pipe, fflush() will
do the trick.-----Original Message-----

Subject: [HACKERS] A portable code questionIn the little fix I came up with for psql last night, I need to be
able to ensure that something sent to a pipe (and then to stdout)
completes before issuing the prompt directly to stdout.I did this with: "system ('sleep 1');", but I'm fairly sure that is
not portable nor does it ENSURE completion.What's the proper way to do this? And what's a good book on writing
portable code?
