This is not 'Sync flag controlled, yet. This makes sense because you will usually be reading data from the front of the file. Choose a name prefix for the library, more than two characters long.

If you use fopen() on a file that does not exist, it will create it, given that the file is opened for writing (w) or appending (a). The example. This function is identical to calling fopen(), fwrite() and fclose() successively to write data to a file.
