SysV Signals and System Calls

[Fred Cox]

We have a large program initially written on suns, which we now need
to port to various System V machines.  The problem that we are coming
up with is that in BSD 4.2 systems, systems calls are not disturbed
by signals, while System V system calls return an error.  We need signals
for timer events.  What do people do in those cases where they are
using packages, like X Windows, which wait in system calls (read) while
signals may be occurring?
