Class TFindThread

class TFindThread : public TFindHandleBase;

Description

Searches for threads by pattern matching against the names of thread 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 TFindThread::Next(TFullName &) repeatedly to find successive threads whose names match the current pattern. A successful call to TFindThread::Next(TFullName &) means that a matching thread has been found. To open a handle on this thread, call RThread::Open(const TDesC &,TOwnerType) and pass a reference to this TFindThread.

Derivation

• TFindHandle - No description.

• TFindHandleBase - Base class for searching for global kernel objects.

• TFindThread - Searches for threads by pattern matching against the names of thread objects.

Members

Defined in TFindThread:

• Next(TFullName &)Gets the full name of the next global thread which matches the match pattern.
• TFindThread()Constructs this object with a default match pattern.
• TFindThread(const TDesC &)Constructs this object with the specified match pattern.

Inherited from TFindHandleBase:

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

• RThreadA handle to a thread.

inline TFindThread();

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 &).

See also:

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

inline TFindThread(const TDesC &aMatch);

Description

Constructs this object with the specified match pattern.

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

Parameters

const TDesC16 &aMatch

See also:

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

IMPORT_C TInt Next(TFullName &aResult);

Description

Gets the full name of the next global thread which matches the match pattern.

Parameters

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

Return value

TInt KErrNone if successful, otherwise one of the other system-wide error codes.
