Ok, thanks, that was something which I did not understand. So... perhaps the paragraph where poll(2) mentions significance should read like this?
.Pp The design of poll was adapted from STREAMS (IEEE Std 1003.1). Typically, in OpenBSD, POLLIN indicates that read(2) may be used without blocking, while POLLPRI and POLLRDBAND are equivalent to each other and indicate that a byte of data may be read using recv(2) without blocking. Any other significance is device specific and will be documented in the device's manual page. Thanks, -- Raul On Mon, Feb 16, 2015 at 3:21 PM, Todd C.
