Tries to lock the interprocess_mutex, returns false when interprocess_mutex is already locked, returns true when success. More... | |

Wraps a interprocess_mutex that can be placed in shared memory and can be shared between processes.
Allows several locking calls by the same process. Allows timed lock tries

Constructor.
Throws interprocess_exception on error.

Destructor.
If any process uses the mutex after the destructor is called the result is undefined. Does not throw.
|
inline |
Effects: The calling thread tries to obtain ownership of the mutex, and if another thread has ownership of the mutex, it waits until it can obtain the ownership.
If a thread takes ownership of the mutex the mutex must be unlocked by the same mutex. The mutex must be unlocked the same number of times it is locked. Throws: interprocess_exception on error.

Tries to lock the interprocess_mutex, if interprocess_mutex can't be locked before abs_time time, returns false.
The mutex must be unlocked the same number of times it is locked. Throws: interprocess_exception if a severe error is found

Effects: The calling thread releases the exclusive ownership of the mutex.
If the mutex supports recursive locking, the mutex must be unlocked the same number of times it is locked. Throws: interprocess_exception on error.
