/*

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.
