Not sure this is the best group: my question concerns the actual
Posix standard, and what it says.

Basically, is it legal to copy a pthread_mutex_t or a
pthread_cond_t, and use the copy? If not (which is the only
answer which makes sense to me), where does the Posix
specification say this? If so, what does it mean: what happens,
for example, if a copy a mutex which is held by a thread, wait
on the copy, and the holding thread frees the original?
