-.TH FDATASYNC 2 2007-07-26 "Linux" "Linux Programmer's Manual"
-.SH NAME
-fdatasync \- synchronize a file's in-core data with that on disk
-.SH SYNOPSIS
-.B #include <unistd.h>
-.sp
-.BI "int fdatasync(int " fd );
-.sp
-.in -4n
-Feature Test Macro Requirements for glibc (see
-.BR feature_test_macros (7)):
-.in
-.sp
-.BR fdatasync ():
-_POSIX_C_SOURCE\ >=\ 199309L || _XOPEN_SOURCE\ >=\ 500
-.SH DESCRIPTION
-.BR fdatasync ()
-flushes all data buffers of a file to disk (before the system
-call returns).
-It resembles
-.BR fsync (2)
-but is not required to update metadata such as the file last access time.
-
-Applications that access databases or log files often write a tiny
-data fragment (e.g., one line in a log file) and then call
-.BR fsync (2)
-immediately in order to ensure that the written data is physically
-stored on the harddisk.
-Unfortunately,
-.BR fsync (2)
-will always initiate two write operations: one for the newly written
-data and another one in order to update the modification time stored
-in the inode.
-If the modification time is not a part of the transaction
-concept
-.BR fdatasync ()
-can be used to avoid unnecessary inode disk write operations.
-.SH "RETURN VALUE"
-On success, zero is returned.
-On error, \-1 is returned, and
-.I errno
-is set appropriately.
-.SH ERRORS
-.TP
-.B EBADF
-.I fd
-is not a valid file descriptor open for writing.
-.TP
-.B EIO
-An error occurred during synchronization.
-.TP
-.BR EROFS ", " EINVAL
-.I fd
-is bound to a special file which does not support synchronization.
-.SH "CONFORMING TO"
-POSIX.1-2001.
-.SH AVAILABILITY
-On POSIX systems on which
-.BR fdatasync ()
-is available,
-.B _POSIX_SYNCHRONIZED_IO
-is defined in
-.I <unistd.h>
-to a value greater than 0.
-(See also
-.BR sysconf (3).)
-.\" POSIX.1-2001: It shall be defined to -1 or 0 or 200112L.
-.\" -1: unavailable, 0: ask using sysconf().
-.\" glibc defines them to 1.
-.SH NOTES
-In Linux 2.2 and earlier,
-.BR fdatasync ()
-is equivalent to
-.BR fsync (2),
-and so has no performance advantage.
-.SH "SEE ALSO"
-.BR fsync (2),
-.BR sync_file_range (2)
