- The ssyynncc() function forces a write of dirty (modified) buffers in the
- block buffer cache out to disk. The kernel keeps this information in core
- to reduce the number of disk I/O transfers required by the system. As
- information in the cache is lost after a system crash a ssyynncc() call is
- issued frequently by the user process update(8) (about every 30 seconds).
-
- The function fsync(2) may be used to synchronize individual file descrip-
- tor attributes.
