Berkeley DB: memp_fsync
memp_fsync
|
 
|
#include <db.h>
int
memp_fsync(DB_MPOOLFILE *mpf);
Description
The memp_fsync function writes all pages associated with the
DB_MPOOLFILE, which were marked as modified using
memp_fput or memp_fset, back to the source file. If
any of the modified pages are also pinned (that is, this or
another process currently refers to them), memp_fsync will
ignore them.
The memp_fsync function returns a non-zero error value on failure, 0 on success, and returns DB_INCOMPLETE if there were pages that were modified
but that memp_fsync was unable to write immediately.
Errors
The memp_fsync function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the memp_fsync function may fail and return
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
