ACE synchronization Typde type and macro definition

ACE synchronization Typde type and macro definition

Typical lock whistle macro

ACE_GUARD_RETURN (ACE_SYNCH_MUTEX, ACE_MON, THIS-> Mutex_, -1);

ACE_SYNCH_MUTEX defines in the file below

SYNCH_T.H

Synchronous object macro definition,

Mainly provide typedef unified multi-thread synchronization definition

Class ACE_EXPORT ACE_MT_SYNCH
