Detailed 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().
After construction, call TFindProcess::Next() repeatedly to find successive processes whose names match the current pattern. A successful call to TFindProcess::Next() means that a matching process has been found. To open a handle on this process, call RProcess::Open() and pass a reference to this TFindProcess.

Constructor & Destructor Documentation
◆ TFindProcess() [1/2]
|
inline |
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().

◆ TFindProcess() [2/2]
|
inline |
Constructs this object with the specified match pattern.
A new match pattern can be set after construction by calling the TFindHandleBase::Find().

Member Function Documentation
◆ Next()
| IMPORT_C TInt TFindProcess::Next | ( | TFullName & | aResult | ) |
Gets the full name of the next process which matches the match pattern.
- Parameters
-
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.
