ReadFile()
WriteFile()
    The function starts writing data to the file at the position indicated by the file pointer. After the write operation has been completed, the file pointer is adjusted by the number of bytes actually written, except when the file is opened with FILE_FLAG_OVERLAPPED. If the file handle was created for overlapped input and output (I/O), the application must adjust the position of the file pointer after the write operation is finished.

    nNumberOfBytesToWrite
        Number of bytes to write to the file.
        A value of zero specifies a null write operation. A null write operation does not write any bytes but does cause the time stamp to change.
            c.f. SetEndOfFile()

        Named pipe write operations across a network are limited to 65,535 bytes.
