3.2.2.3 Data Segments

Whereas under DOS the programmer had to pay special attention to the data segments used in the extension subroutine, under Unix the dynamic linking of shared objects handles the data segment allocation automatically. Therefore, no special consideration of data segments is needed.

The next section is the Extension Reference, which fully describes, for all including extensions, every option to the user and every line of source for the developer. By following the rules detailed here and using examples from the reference section, the fearless user will be able to create some very powerful extensions.
