Chapter 5:
Signals
Few people appreciate the truly insidious nature
of asynchronous events until they encounter
an irreproducible problem.
This chapter discusses signals and their
effect on processes. The chapter also
covers the new POSIX.1b signal handling and
asynchronous I/O facilities. The new signal handling
is particularly nice, allowing queueing of signals
and the transmittal of additional information
to the signal handler.
