FSYNC(2)		    BSD System Calls Manual		      FSYNC(2)

NAME
     fsync — synchronize a file's in-core state with that on disk

SYNOPSIS
     #include <unistd.h>

     int
     fsync(int fd);

DESCRIPTION
     Fsync() causes all modified data and attributes of fd to be moved to a
     permanent storage device.	This normally results in all in-core modified
     copies of buffers for the associated file to be written to a disk.

     Fsync() should be used by programs that require a file to be in a known
     state, for example, in building a simple transaction facility.

RETURN VALUES
     A 0 value is returned on success.	A -1 value indicates an error.

ERRORS
     The fsync() fails if:

     [EBADF]		fd is not a valid descriptor.

     [EINVAL]		fd refers to a socket, not to a file.

     [EIO]		An I/O error occurred while reading from or writing to
			the file system.

SEE ALSO
     sync(2), sync(8), update(8)

HISTORY
     The fsync() function call appeared in 4.2BSD.

4.2 Berkeley Distribution	 June 4, 1993	     4.2 Berkeley Distribution
