open-flags

A 32-bit word indicating the priority algorithm used to grant locks:

Bit 0

0	Readers and writers have interleaved priority; that is, if a write request is issued, any further read requests will block until the first write request is granted and finished
1	Read requests always have priority, possibly leading to writer starvation.

Bits 1-31

Reserved and should be set to zero.

monitor-handle: The monitor handle.
return-code: A value of 0 indicates that the call was successful. Any other value indicates an error. See RETURN-CODE Values For Synchronization Routines.

If open-flags bit 0 is set to 0, and nested read locks are requested, then single thread deadlock is possible.
