Hello all,
is it possible for a thread to destroy a mutex it has previously locked ? or
does it have to be unlocked first ?
As part of a thread-shutdown routine, I want to destroy a mailbox whose
messages are in shared memory, therefore I mutex the messages, destroy the
mailbox, destroy the shared memory and release threads waiting on the mutex
and then destroy it ... all in one go ...
The second question: I haven't been able to find any documentation on the
mbox variable, used in initialising a mailbox. If I have to reserve memory
for it would be nice to know what size it has. any pointers (excuse the pun)
?
Thanks
Hans
