This data structure is meant to be used within a method or function... It performs automatic acquisition and release of a parameterized synchronization object ACE_LOCK.
The ACE_LOCK class given as an actual parameter must provide, at the very least the acquire(), tryacquire(), release(), and remove() methods.
Implicitly and automatically acquire (or try to acquire) the lock. If block is non-0 then acquire() the ACE_LOCK, else tryacquire() it.
|
inline |
Initialize the guard without implicitly acquiring the lock. The become_owner parameter indicates whether the guard should release the lock implicitly on destruction. The block parameter is ignored and is used here to disambiguate with the preceding constructor.
Implicitly release the lock.
Helper, meant for subclass only.
|
inline |
Explicitly acquire the lock.
|
inline |
Relinquish ownership of the lock so that it is not released implicitly in the destructor.
void ACE_Guard< ACE_LOCK >::dump | ( | void | ) | const |
Dump the state of an object.
|
inline |
true if locked, false if couldn't acquire the lock (errno will contain the reason for this).

|
inline |
Explicitly release the lock, but only if it is held!

Explicitly remove the lock.
