[ECOS] Cyg_Binary_Semaphore class

[Richard Wicks <rich at accetnetwork dot com>]

I was poking through the code and I ran across binary semaphores here:

${ECOS_REPOSITORY}/kernel/current/src/sync/bin_sem.cxx

I didn't realize these were implemented in the system.  I didn't see them 
covered in the ecos reference manual here:

http://sources.redhat.com/ecos/docs-latest/pdf/ecos-ref.pdf

Are binary semaphores new?  How do I access them from C code instead of C++?

thanks,
