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.

| ) |
Initialize the mutex.
| ACE_Mutex::~ACE_Mutex | ( | void | ) |
Implicitly destroy the mutex.
| ACE_Mutex::ACE_Mutex | ( | const ACE_Mutex & | ) | [private] |
| int ACE_Mutex::acquire | ( | void | ) | [inline] |
Acquire lock ownership (wait on queue if necessary).
| int ACE_Mutex::acquire | ( | ACE_Time_Value * | tv | ) | [inline] |
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.
| int ACE_Mutex::acquire | ( | ACE_Time_Value & | tv | ) | [inline] |
Block the thread until the mutex is acquired or tv times out, in which case -1 is returned and errno == ETIME.
| int ACE_Mutex::acquire_read | ( | void | ) | [inline] |
Acquire mutex ownership.
This calls acquire and is only here to make the ACE_Mutex interface consistent with the other synchronization APIs.
| int ACE_Mutex::acquire_write | ( | void | ) | [inline] |
Acquire mutex ownership.
This calls acquire and is only here to make the ACE_Mutex interface consistent with the other synchronization APIs.
| void ACE_Mutex::dump | ( | void | ) | const |
Dump the state of an object.
| const ACE_mutex_t & ACE_Mutex::lock | ( | void | ) | const [inline] |
Return the underlying mutex.
| ACE_mutex_t & ACE_Mutex::lock | ( | void | ) | [inline] |
| void ACE_Mutex::operator= | ( | const ACE_Mutex & | ) | [private] |
| int ACE_Mutex::release | ( | void | ) | [inline] |
Release lock and unblock a thread at head of queue.
| int ACE_Mutex::remove | ( | void | ) | [inline] |
Explicitly destroy the mutex.
| int ACE_Mutex::tryacquire | ( | void | ) | [inline] |
Conditionally acquire lock (i.e., don't wait on queue).
errno is set to EBUSY. | int ACE_Mutex::tryacquire_read | ( | void | ) | [inline] |
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.
errno is set to EBUSY. | int ACE_Mutex::tryacquire_write | ( | void | ) | [inline] |
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.
errno is set to EBUSY. | int ACE_Mutex::tryacquire_write_upgrade | ( | void | ) | [inline] |
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.
Declare the dynamic allocation hooks.
| ACE_mutex_t ACE_Mutex::lock_ |
Mutex type supported by the OS.
| bool ACE_Mutex::removed_ |
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.
