Unit Bufio; Interface
|

*****************************************************************************
|
||
|
||
Bufio implements the structured reading of the imput stream. As such, it
|
||
will handle the necessary byte-swapping that must occur when reading a
|
||
native Macintosh file.
|
||
|
||
This interface will also shield the calling application from knowledge of
|
||
the source format (file vs. memory).
|
||
|
||
Module Prefix: IO
