Class TFindProcess

class TFindProcess : public TFindHandleBase;

Description

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

Members

Defined in TFindProcess:

• Next(TFullName &)Gets the full name of the next process which matches the match pattern.
• TFindProcess()Constructs this object with a default match pattern.
• TFindProcess(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.

See also:

• RProcessA handle to a process.

inline TFindProcess();

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 TFindProcess(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 process which matches the match pattern.

Parameters

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

Return value

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