Detailed Description

RAII class creating a critical section.

Note

: everything here MUST be used ONLY from the main thread. When called from a thread of the pool it can deadlock.

: the multi-threading mode MUST NOT be changed in the RAII MultiThreadingCriticalSection body.

: starting and stopping the dhcp thread pool should be handled in the main thread, if done on one of the processing threads will cause a deadlock. This is mainly useful in hook commands which handle configuration changes.
