Portable wrapper of an OS-level mutex for intra-process synchronization.
Declared in <bslmt_mutex.h>
class Mutex;This class implements a lightweight, portable wrapper of an OS-level mutex lock to support intra-process synchronization. The behavior is undefined if the lock method of this class is invoked more than once on the same mutex object in the same thread without an intervening call to unLock.
| Name | Description |
|---|---|
NativeType | NativeType is an alias for the underlying OS-level mutex type. It is exposed so that other bslmt components can operate directly on this mutex. |
| Name | Description |
|---|---|
Mutex [constructor] | Create a mutex object in the unlocked state. This method does not return normally unless there are sufficient system resources to construct the object. |
~Mutex [destructor] | Destroy this mutex object. The behavior is undefined if the mutex is in a locked state. |
lock | Acquire a lock on this mutex, blocking if necessary. |
nativeMutex | Return a reference to the underlying OS-level mutex. |
tryLock | Attempt to acquire a lock on this mutex without blocking. |
unlock | Release a previously acquired lock on this mutex. |
