SYNC(2)                   OpenBSD Programmer's Manual                  SYNC(2)

     sync - synchronize disk block in-core status with that on disk

     #include <unistd.h>


     The sync() 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 sync() 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.

     fsync(2),  sync(8),  update(8)

     sync() may return before the buffers are completely flushed.

     A sync() function call appeared in Version 6 AT&T UNIX.
