Why Our Own Binary Stream?
The idea behind this article is that you often need a way to store your data in some binary files. With REALbasic, on the Mac you can often simply use BinaryStream.WritePString to write a short string to a binary file, but this method has some limitations. First, a Pascal string has a maximum of only 255 characters, which may not be sufficient for uses such as the printer setup string (which is a few kilobytes in size on Mac OS X). Second, the string encoding is not stored inside the file, so you need to convert the encoding before saving.
This article shows you, in source code, how to make a cross platform binary stream which should work on Mac OS X, Mac OS Classic, Windows, and even Linux.
Implementation of our CrossBinaryStream class
Initialization: The Constructor
Make a new class and call it "CrossBinaryStream". Open it and add a private property "stream as binarystream". Inside this property we will save a reference to the target BinaryStream.
