ax_sys_dev_poll

Synopsis

   AX_SYS_DEV_POLL([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])

Description

This macro tests for the presence of /dev/poll support in the build environment. It checks that the needed structure (dvpoll) is available, with the standard fields. /dev/poll is most often seen under Solaris.

Note that it does not attempt to actually open /dev/poll – you should test for errors when you open it and then fall back to poll() if it is unavailable.
