class TRedirectOutputGuard


TRedirectOutputGuard

This class provides output redirection to a file in a guaranteed
exception safe way. Use like this:
{
TRedirectOutputGuard guard(filelog, mode);
... // do something
}
when guard goes out of scope output is automatically redirected to
the standard units in the TRedirectOutputGuard destructor.
The exception mechanism takes care of calling the dtors
of local objects so it is exception safe.
The 'mode' options follow the fopen write modes convention; default
is "a".
