Conventions in This Book

Throughout this book, I have used the following typographic conventions:

Constant width

indicates a language construct such as a language statement, a constant, or an expression. Lines of code also appear in constant width, as do function and method prototypes and variable and parameter names.

Italic

represents intrinsic and application-defined functions, method names, the names of system elements such as directories and files, and Internet resources such as web documents and email addresses. New terms are also italicized when they are first introduced.

Constant width italic

in prototypes or command syntax indicates replaceable parameter names.
