Last change on this file since 5870ac55 was 5870ac55, checked in by Joel Sherrill <joel.sherrill@…>, on 01/05/00 at 22:19:21

Added support for simple binary semaphores in addition to the high
power binary/mutex style semaphores already supported by RTEMS. This
was done at the request of Eric Norum <eric@…> in support
of his effort to port EPICS to RTEMS. This change consisted of
changing the nesting_allowed boolean into a lock_nesting_behavior
enumerated value as well as allowing the core mutex object to optionally
support ensuring that the holder of a binary semaphore released it.
Finally, a more subtle enhancement was to allow the non-holder to release
a priority inheritance/ceiling mutex and still allow the holding task
to return to its original priority.
