** [tickets:#580] base: Add utilility function for poll() that handles EINTR**
**Status:** accepted

Add utility functions for poll() and ppoll(), that handle the error case when
errno == EINTR. Handling of the error code EINTR from poll() requires more than
just a simple loop in the case when poll() is used with a time-out, since we
need to keep track of how long time we have waited so far, and subtract this
from the time-out time for the next call to poll(). By introducing an utility
function for this, we won't have to duplicate this code at all places where
poll() is used.
The poll() utility function is needed for the solution of ticket [#452], but a
separate ticket is created for it since the utility function is useful by
itself.
