Re: Win32 Event vs Conditional variable


A condition variable is probably the best way to wait for a message to
arrive.


Not on windows, because it has a message queue mechanism already.
Not on unix because you might also wait for a message (file descriptor
event).

My generic app framework (runtime of the eiffel compiler i'm
maintaining) uses
a little bit more complicated mechanism. Depending on the thread -
main thread
always wait on a "semaphore" pipe because this is important for the
GUI's libs
which all run in the main thread and normally only have a mechanism to
wait
on file descriptors - and the events that might occur.

Maybe the world would be better if unix could unify the API's and
allow to wait on a semaphore/condition variable and on a file
descriptor but the API is not as well implemented as the WIndows
Kernel API.
