Typographical Conventions

Italics

Filenames, IRIX command names, function parameters, and book titles.

Fixed-width

Code examples and system output.

Fixed-width bold

User input.

Bold

Function names, with parentheses following the name--for example glPolygonMode(), arguments to command line options.

Note: In the "New Functions" sections in the extensions chapters, regular font is used for function names. This avoids large blocks of boldface text, which would be difficult to read.
