Hello all,
Pardon my ignorance, and please tolerate my sloth, but is it possible
(and easy) to run skins side-by-side and have them communicate through
IPCs? So I'd like to run a process that uses VxWorks calls, and then
another one that uses POSIX, and yet have them communicate via one or
two semaphores and shared memory.
TIA,
-Nate

Most services (including shared memory and semaphores) of the POSIX skin
may be used by threads created by other skins. The exceptions to this
rule are the services related to signals and cancellation. In case of
doubt, you may have a look at POSIX skin documentation; it should
document explicitely which services are restricted to which contexts.
