read_begin()

uint32_t MayaFlux::Memory::Seqlock::read_begin ( ) const

inlinenoexcept

Begin a read: spin until the counter is even, return the snapshot.

The caller reads the guarded data after this returns, then calls read_retry() to verify no write overlapped.

Returns

Even sequence snapshot to pass to read_retry().
