// //
19
// This class provides output redirection to a file in a guaranteed //
20
// exception safe way. Use like this: //
21
// { //
22
// TRedirectOutputGuard guard(filelog, mode); //
23
// ... // do something //
24
// } //
25
// when guard goes out of scope output is automatically redirected to //
26
// the standard units in the TRedirectOutputGuard destructor. //
27
// The exception mechanism takes care of calling the dtors //
28
// of local objects so it is exception safe. //
29
// The 'mode' options follow the fopen write modes convention; default //
30
// is "a". //
31
