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.
Download the latest version of ax_sys_dev_poll.m4 or browse the macro’s revision history.
