sys_fdatasync [fs/buffer.c]
Flushes all data buffers of a file to disk. This system call is identical to sys_fsync except it only flushes user data, not the meta data like the st_atime or st_mtime (respectively, time of last access and time of last modification). Arguments
eax | 148
ebx | File descriptor.
Return values If the system call succeeds the return value is 0. If the system call fails the return value is one of the following errno values (depending on the file systems other error values may be returned):
`-EBADF` | `ebx is not a valid file descriptor open for writing.`
`-EROFS, -EINVAL` | `File descriptor is bound to a special file which does not support synchronization.`
`-EIO` | `An error occurred during synchronization.`
Remarks The flushing is finished before the system call returns. Compatibility n/a
