SYNC(2-BSD)         RISC/os Reference Manual          SYNC(2-BSD)



NAME
     sync - update super-block

SYNOPSIS
     sync()

DESCRIPTION
     sync causes all information in core memory that should be on
     disk to be written out.  This includes modified super
     blocks, modified i-nodes, and delayed block I/O.

     sync should be used by programs that examine a file system,
     for example fsck, df, etc.  sync is mandatory before a boot.

SEE ALSO
     fsync(2).
     sync(1M) in the System Administrator's Reference Manual.

BUGS
     The writing, although scheduled, is not necessarily complete
     upon return from sync.
