Hi, allow me to repost this query of mine that went
without much attention at first try...
As the docs do not explicitly say otherwise, I guess I must assume that
boost::shared_mutex is not recursive with respect to unique ownership,
that is, the following behavior ensues:
shared_mutex mutex;
lock_guard lock1(mutex);
lock_guard lock2(mutex); // DEADLOCK
Is this so? In case boost::shared_mutex is indeed non-recursive, I've
read the following assertion on Hinnant's paper N2406
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2406.html ):
"A recursive shared mutex could be built upon shared_mutex if desired,
but this is not proposed."
Does anyone has a reference on how to construct a recursive
shared_mutex from a non-recursive one?
Thank you,
