Detailed Description
A logstream is an ostream useful for logging.
Each line is preceeded by the date and an application-determined identification string.
- Warning:
- Output is line-oriented and buffered, i.e. output will be kept until '\n' is seen, at which time the whole line (preceeded by prefix and date information) will be written to the output.

| Dv::Util::logstream::logstream | ( | const std::string & | path, | |
| const std::string & | prefix | |||

Creates ofstream for path.
The stream will be opened with mode ios:app, i.e. a seek to the end of the stream will be performed before each output operation.
- Parameters:
-
path on which log output will be written. prefix each output line will start with the date and this prefix string

Constructor.
- Parameters:
-
stream existing stream on which output will be written. prefix each output line will start with the date and this prefix string
