Still: Does ReleaseSRWLockExclusive notify other threads?
Of course? How else would a lock work, it must release other waiters?
It might not be a fair lock though, which is not a problem for this situation,
which does not require fair locking.
Functionally, the INIT_ONCE looks interesting. But, like Takashi Yano mentioned,
how would you make it fit into a pthread_once_t that is defined as
struct { pthread_mutex_t mutex; int state; }
?
Something like:
struct once {
union {
pthread_mutex_t old_mutex_field_for_size_compatibility;
SRWLOCK lock = SRWLOCK_INIT;
};
int state;
};
