Revision 2d02ec653355e4f558bd3bb2ef0e442520de26f9 authored by Bradley Grainger on 16 June 2014, 22:41:46 UTC, committed by Bradley Grainger on 16 June 2014, 22:41:46 UTC
Some platforms, particularly Windows, do not have a single method that can release both a held reader lock and a held writer lock; instead, a separate method (ReleaseSRWLockShared or ReleaseSRWLockExclusive) must be called in each case. This may also be necessary to back MutexRW with a shared_mutex in C++14; the current language proposal includes both an unlock() and a shared_unlock() method.
