Class TFindChunk

class TFindChunk : public TFindHandleBase;

Description

Searches for all global chunks by pattern matching against the names of (Kernel side) chunk objects.

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(const TDesC &).

After construction, call TFindChunk::Next(TFullName &) repeatedly to find successive chunks whose names match the current pattern. A successful call to TFindChunk::Next(TFullName &) means that a matching chunk has been found.

Members

Defined in TFindChunk:

• Next(TFullName &)Finds the full name of the next chunk which matches the match pattern.
• TFindChunk()Constructs this object with a default match pattern.
• TFindChunk(const TDesC &)Constructs the object with the specified match pattern.

Inherited from TFindHandleBase:

• Find(const TDesC &)Sets a new match pattern.
• TFindHandleBase(const TDesC &)Constructor with match pattern.

inline TFindChunk();

Description

Constructs this 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 TFindHandleBase::Find(const TDesC &).

inline TFindChunk(const TDesC &aMatch);

Description

Constructs the object with the specified match pattern.

A new match pattern can be set after construction by calling TFindHandleBase::Find(const TDesC &).

Parameters

const TDesC16 &aMatch The match pattern.

IMPORT_C TInt Next(TFullName &aResult);

Description

Finds the full name of the next chunk which matches the match pattern.

Parameters

TBuf &aResult A reference to a TBuf descriptor with a defined maximum length. If a matching chunk is found, its full name is set into this descriptor. If no matching chunk is found, the descriptor length is set to zero.

Return value

TInt KErrNone, if a matching chunk is found; KErrNotFound otherwise.
