sync(2) System Calls sync(2) NAME sync - update super block SYNOPSIS #include <unistd.h> void sync(void); DESCRIPTION The sync() function writes all information in memory that should be on disk, including modified super blocks, modified inodes, and delayed block I/O. Unlike fsync(3C), which completes the writing before it returns, sync() schedules but does not necessarily complete the writing before return- ing. USAGE The sync() function should be used by applications that examine a file system, such as fsck(1M), and df(1M), and is mandatory before reboot- ing. SEE ALSO df(1M), fsck(1M), fsync(3C) SunOS 5.9 5 Jul 1990 sync(2)
