Searches for PDD factory objects by pattern matching against the names of PDD factory objects.
A PDD factory object is an instance of a DPhysicalDevice derived class.
The match pattern can be set into this object at construction; it can also be changed at any time after construction by using TFindHandleBase::Find().
After construction, call TFindPhysicalDevice::Next() repeatedly to find successive PDD factory objects whose names match the current pattern. A successful call to TFindPhysicalDevice::Next() means that a matching PDD factory object has been found.
The name of a PDD factory object is set by its Install() member function as part of the construction process.
| TFindPhysicalDevice | ( | ) | [inline] |
Constructs the PDD factory 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.

| TFindPhysicalDevice | ( | const TDesC & | aMatch | ) | [inline] |
Constructs the PDD factory object with a specified match pattern.
A new match pattern can be set after construction by calling TFindHandleBase::Find().

| Parameter | Description |
|---|---|
| aMatch | The match pattern. |
Finds the full name of the next PDD factory object which matches the match pattern.
| Parameter | Description |
|---|---|
| aResult | A reference to a TBuf descriptor with a defined maximum length. If a matching PDD factory object is found, its full name is set into this descriptor. If no matching PDD factory object is found, the descriptor length is set to zero. |
Returns: KErrNone, if a matching PDD factory object is found; KErrNotFound otherwise.
