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.
