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