| Subject: | PIPE and FIFO |
Hello,
sorry for beeing a little bit of topic, but it is a technical question and so I thing its ok to ask here.
What are the restrictions of PIPE: and FIFO:? Can I use them like a normal File?
I want to do the followig:
I have an AIFF-audiofile, some 100 MBytes in size. I want to convert this file with "sox" into Sun .au format. This new Sun .au file is one input file of an animation/sound mixer program. As all files are very big I would like to avoid temporary files.
So I dream of something like this:
Shell_1:
sox Sound.Aiff Pipe:Sound.au
(Write to pipe:)
Shell_2:
SndAnimMixer Pipe:Sound.au AnimFile Resultfile
(read from pipe:)
Is that possible? If yes, what restrictions apply to "Pipe-Files"? Can I as programmer seek in a pipe-file and rewind again?
Lets say I want to read parts of a file in a non continous order. Is that possible? Can I read parts of that file multiple times? If yes, how does it work internally?
Kind regards Alexander Fritsch
