| 5 | Class handling the writing of slow data. Strings to be written in the
|
|---|
| 6 | slow data file are checked that they do not contain control characters.
|
|---|
| 7 |
|
|---|
| 8 | 1. Call constructor with desired identification and directory
|
|---|
| 9 | for slow data file. The public ErrorCode variable will be zero
|
|---|
| 10 | if successful, otherwise contain the relevant errno.
|
|---|
| 11 | 2. Use NewEntry() to start a new entry with given variable name. A text
|
|---|
| 12 | as second argument is optional.
|
|---|
| 13 | 3. If text should be added to an open entry, use AddToEntry(). It can
|
|---|
| 14 | process printf()-style formatting.
|
|---|
| 15 | 4. The slow data file will be closed upon destruction of the instance.
