Create initializes a TFileReader using the provided AFileName. It will allocate a buffer of ABufferSize bytes for faster reading of data. If no buffer size is specified, BUFFER_SIZE will be used. If the ABufferSize argument is less than MIN_BUFFER_SIZE, then MIN_BUFFER_SIZE bytes will be used.
The AMode can be used to specify the mode in which to open the file. This is one of the fmOpenRead and fmShare* constants which can be used in a TFileStream constructor. The file must be opened for reading.
If AStream is Nil, an #rtl.sysutils.EArgumentException exception will be raised.
