Final Accepted Text
Summary 0001160: Condition for EAGAIN inverted.
Description I read under read():
ERRORS

    These functions shall fail if:

    [EAGAIN]
        The file is neither a pipe, nor a FIFO, nor a socket, the O_NONBLOCK flag is set for the file descriptor, and the thread would be delayed in the read operation.

Doesn't make sense. Documentation for several other UNIX-y systems
says such as "is either a pipe, a FIFO, or a socket, ..."
Desired Action Change "is neither a pipe, nor a FIFO, nor a socket, ..." to
"is either a pipe, a FIFO, or a socket, ..."

(Should this apply also to a TTY?)

Thanks,
gil

The current text is correct. "These functions" includes pread() which fails with ESPIPE not EAGAIN. Further down there is another EAGAIN that is just for read().
