The npt-and program
npt-and listens to a fifodir until it has been notified with
a set of events. It's a simple interface to the
nptrigger_wfa()
library call.
Interface
npt-and fifodir event1 event2 ...
npt-and blocks until fifodir has been notified with
all the eventi. Then it exits 0.
You should use npt-and with
maximumtime to ensure that it does not
block forever.
Notes
The goal of npt-and is to implement portable checkpoint
conjunction.
