Is anyone here interested in SIGPOLL support in ksh93 (after the
.sh.sig support has been fixed), i.e. provide a way to open a fd with
O_ASYNC and listen to the SIGIO or SIGPOLL signals.
I assume you know about the poll(1) builtin ksh93 now supports.
What's the purpose of SIGPOLL support? Trying to implement push
notification for socket I/O instead of pull via poll(1)?
instead of make an active loop to see if there is something to read on
some fd, you may do anything you want until a SIGIO trap raise some
handler which know that there is something to read.
c'est plus clair maintenant ? :-)
