|class TFindMutex : public TFindHandleBase|
|Public Member Functions|
|TFindMutex(const TDesC &)|
|IMPORT_C TInt||Next(TFullName &)|
|TFindHandleBase::Find(const TDesC &)|
|TFindHandleBase::TFindHandleBase(const TDesC &)|
Finds all global mutexes whose full names match a specified pattern.
The match pattern can be set into the object at construction; it can also be changed at any time after construction by using the Find() member function of the base class.
After construction, the Next() member function may be used repeatedly to find successive global mutexes whose full names match the current pattern.
A successful call to Next() means that a matching global mutex has been found. To open a handle on this mutex, call the Open() member function of RMutex and pass a reference to this TFindMutex object.
Pattern matching is part of descriptors behaviour.
|TFindMutex||(||const TDesC &||aMatch||)||[inline]|
Constructs this object with the specified match pattern.
After construction, the object contains a copy of the supplied match pattern; the source descriptor can, therefore, be safely discarded.
See also: TFindHandleBase::Find
|aMatch||The match pattern.|
Finds the next global mutex whose full name matches the match pattern.
If a global mutex with a matching name is found, the function copies its full name into the specified descriptor. It also saves the find-handle associated with the global mutex into the TFindHandleBase part of this object.
|aResult||A reference to a descriptor with a defined maximum length. If a matching global mutex is found, its full name is set into this descriptor. If no matching global mutex is found, the descriptor length is set to zero.|
Returns: KErrNone if a matching global mutex is found; KErrNotFound otherwise.
