Re: I/O semantics of pipe and FIFO.

While it may be true that one or more systems have this "feature", the script you have provided does not demonstrate that behavior. (And, I am not aware of any system that does behave the way you have described.) Since a writer is blocked from writing into a FIFO if the FIFO is not open for

Re: I/O semantics of pipe and FIFO.

Found it: http://man.cat-v.org/unix_8th/2/write Should I file an editorial bug on the rationale section of the write() interface, to note that some systems have this feature? Since we've already mentioned the special case of making a zero-length write request.

I/O semantics of pipe and FIFO.

Hi all. I couldn't remember where I saw it saying, that when reading from a pipe or a FIFO, the read syscall returns the content of at most one write call. It's a bit similar to the message-nondiscard semantics of dear old STREAM. Currently, I'm reading through the text to find out a bit
