25 The fdatasync() function shall force all currently queued I/O operations associated
26 with the file indicated by file descriptor fildes to the synchronized I/O completion
27 state.The functionality shall be equivalent to fsync() with the symbol ->
28 _POSIX_SYNCHRONIZED_IO defined, with the exception that all I/O operations shall be
29 completed as defined for synchronized I/O data integrity completion.If successful,
30 the fdatasync() function shall return the value 0; otherwise, the function shall
31 return the value -1 and set errno to indicate the error.
