-.SH DESCRIPTION
-.BR sync ()
-causes all buffered modifications to file metadata and data to be
-written to the underlying filesystems.
-
-.BR syncfs ()
-is like
-.BR sync (),
-but synchronizes just the filesystem containing file
-referred to by the open file descriptor
-.IR fd .
-.SH RETURN VALUE
-.BR syncfs ()
-returns 0 on success;
-on error, it returns \-1 and sets
-.I errno
-to indicate the error.
-.SH ERRORS
-.BR sync ()
-is always successful.
-
-.BR syncfs ()
-can fail for at least the following reason:
-.TP
-.B EBADF
-.I fd
-is not a valid file descriptor.
-.SH VERSIONS
-.BR syncfs ()
-first appeared in Linux 2.6.39;
-library support was added to glibc in version 2.14.
-.SH CONFORMING TO
-.BR sync ():
-SVr4, 4.3BSD, POSIX.1-2001.
-
-.BR syncfs ()
-is Linux-specific.
-.SH NOTES
-Since glibc 2.2.2, the Linux prototype for
-.BR sync ()
-is as listed above,
-following the various standards.
-In glibc 2.2.1 and earlier,
-it was "int sync(void)", and
-.BR sync ()
-always returned 0.
-.SH BUGS
-According to the standard specification (e.g., POSIX.1-2001),
-.BR sync ()
-schedules the writes, but may return before the actual
-writing is done.
-However, since version 1.3.20 Linux does actually wait.
-(This still does not guarantee data integrity: modern disks have
-large caches.)
