SYNC(2) System Calls Manual SYNC(2)
NAME
sync, fsync - update dirty buffers and super-block
SYNOPSIS
#include <unistd.h>
int sync(void)
int fsync(fd)
DESCRIPTION
Sync causes all information in the file system buffers that should be
on disk to be written out. This includes modified super blocks, modi-
fied i-nodes, and delayed block I/O. Fsync does the same thing, but
only for the blocks associated with a specific file descriptor. Under
minix, currently the two calls do the same thing.
SEE ALSO
