Detailed Description
ACE_Mutex wrapper (valid in same process or across processes (depending on TYPE flag)). In general, however, we recommend using ACE_Process_Mutex or ACE_Thread_Mutex rather than ACE_Mutex.
Constructor & Destructor Documentation
Implicitly destroy the mutex.
Member Function Documentation
Acquire lock ownership (wait on queue if necessary).
Block the thread until the mutex is acquired or tv times out, in which case -1 is returned and errno == ETIME.
- Note:
- tv is assumed to be in "absolute" rather than " relative" time. The value of tv is updated upon return to show the actual(absolute) acquisition time.
Block the thread until the mutex is acquired or *tv times out, in which case -1 is returned and errno == ETIME. If tv == 0 then call acquire() directly. Otherwise, block the thread until the mutex is acquired or tv times out, in which case -1 is returned and errno == ETIME.
- Note:
- *tv is assumed to be in "absolute" rather than "relative" time. The value of *tv is updated upon return to show the actual (absolute) acquisition time.
Acquire mutex ownership.
This calls acquire and is only here to make the ACE_Mutex interface consistent with the other synchronization APIs.

Dump the state of an object.
Return the underlying mutex.

Release lock and unblock a thread at head of queue.
Explicitly destroy the mutex.
- Note:
- Only one thread should call this method since it doesn't protect against race conditions.
Conditionally acquire lock (i.e., don't wait on queue).
- Returns:
- -1 on failure. If we "failed" because someone else already had the lock,
errno is set to EBUSY.
Conditionally acquire mutex (i.e., won't block).
This calls tryacquire and is only here to make the ACE_Mutex interface consistent with the other synchronization APIs.
- Returns:
- -1 on failure. If we "failed" because someone else already had the lock,
errno is set to EBUSY.

- Returns:
- -1 on failure. If we "failed" because someone else already had the lock,
errno is set to EBUSY.
This is only here for consistency with the other synchronization APIs and usability with Lock adapters. Assumes the caller already has acquired the mutex and returns 0 in all cases.
Member Data Documentation
Declare the dynamic allocation hooks.
Mutex type supported by the OS.
Keeps track of whether remove has been called yet to avoid multiple remove calls, e.g., explicitly and implicitly in the destructor. This flag isn't protected by a lock, so make sure that you don't have multiple threads simultaneously calling remove on the same object, which is a bad idea anyway.
