Conventions, Typographical
and Otherwise
The following typographical conventions are used throughout the book:
Italic
is used for the names of files, functions, programs, methods, routines, and
options when they appear in the body of a paragraph. Italic is also used for
emphasis and to introduce new terms.
Constant Width
is used in the examples to show the contents of files and the output of com-
mands. In the body of a paragraph, this style is used for keywords, variable
names, classes, objects, parameters, and other code snippets.
Constant Width Bold
is used in the examples to show commands and options that you type literally.
The owl symbol is used to indicate a tip, suggestion, or general note.
The turkey symbol is used to indicate a warning.
Other conventions relate to gender and roles. With respect to gender, I have pur-
posefully alternated my use of the terms “he” and “she” throughout the book. “He”
is used in the odd-numbered chapters and “she” in all of the even-numbered ones.
With respect to roles, I have occasionally distinguished between the tasks of hard-
ware engineers, embedded software engineers, and application programmers in
my discussion. But these titles refer only to roles played by individual engineers,
and it should be noted that it can and often does happen that one individual fills
more than one of these roles.
