communicate with named pipe

Jiansong Li

2/20/2005 3:39:00 PM

I am a newbie of this mailing place but I want to draw a gui for other
program via ruby. That program is written by C++ and creaded two pipe:
mkfifo(read_str,0600)
readfd=open(read_str,O_RDWR)
mkfifo(write_str,0600)
writefd=open(write_str,O_RDWR).
I serched all the subject through the mailing list but can't find useful
information to help me create a named pipe.
Who can give me a hand?

If the C++ program is creating the pipes, you can simply open them as
ordinary files from Ruby.

If you want to create the pipes from Ruby, you'll have to use a system
call:

path = "/path/to/fifo"
system("mkfifo #{path}")

Or wait for the patch in [ruby-talk:91735] to be integrated.

"Small", naturally.
Women tend to be realists.

Exactly. And they probably don't want them slipping off.

Old joke:

Superman and Lois Lane are finally consummating their
relationship. Superman strips down and only has a 2" penis. Lois asks
"Who are you going to please with that?" and he replies "Myself!"
