Communicate with named pipe

ruby-talk
1

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?

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.

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.
