journal_wipe — Wipe journal contents
int journal_wipe ( | journal_t * | journal, |
| int | write); |
Wipe out all of the contents of a journal, safely. This will produce
a warning if the journal contains any valid recovery information.
Must be called between journal_init_*() and journal_load.
If 'write' is non-zero, then we wipe out the journal on disk; otherwise we merely suppress recovery.
