sync(2)

NAME | SYNOPSIS | DESCRIPTION | USAGE | SEE ALSO

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 returning.

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 rebooting.

SEE ALSO

df(1M), fsck(1M), fsync(3C)
