| class TFindSemaphore : public TFindHandleBase |
Finds all global semaphores whose full names match a specified pattern.
The match pattern can be set into the TFindSemaphore object at construction; it can also be changed at any time after construction by using the Find() member function of the TFindHandleBase base class.
After construction, the Next() member function can be used repeatedly to find successive global semaphores whose full names match the current pattern.
A successful call to Next() means that a matching global semaphore has been found. To open a handle on this semaphore, call the RSemaphore::Open() function and pass a reference to this TFindSemaphore.
Pattern matching is part of descriptor behaviour.
| Public Member Functions | |
|---|---|
| TFindSemaphore() | |
| TFindSemaphore(const TDesC &) | |
| IMPORT_C TInt | Next(TFullName &) |
| TFindSemaphore | ( | ) | [inline] |
Constructs the object with a default match pattern.
The default match pattern, as implemented by the base class, is the single character "*".
A new match pattern can be set after construction by calling the Find() member function of the TFindHandleBase base class.
| TFindSemaphore | ( | const TDesC & | aMatch | ) | [inline] |
Constructs this object with the specified match pattern.
A new match pattern can be set after construction by calling TFindHandleBase::Find().
Note that after construction, the object contains a copy of the supplied match pattern; the source descriptor can, therefore, be safely discarded.
| const TDesC & aMatch | A reference to the descriptor containing the match pattern. |
