Conventions Used in This Book

We use the following formatting conventions in this book:

Bold is used for headings in the text.
Italics are used for emphasis and to signify the first use of a term. Italics are also used for functions, email addresses, FTP sites, directory and filenames, and newsgroups.
All code and header examples are in Constant Width.
All numbers in file excerpts and examples are in hexadecimal unless otherwise noted.

All code and header examples use the following portable data types:

BYTE 8-bit unsigned data

CHAR 8-bit signed data

WORD 16-bit unsigned integer

SHORT 16-bit signed integer

DWORD 32-bit unsigned integer

LONG 32-bit signed integer

FLOAT 32-bit single-precision floating point number

DOUBLE 64-bit double-precision floating point number

All source code that we have produced is written in ANSI C. (This is relevant only if you are still using one of the older compilers.)

All World Wide Web and FTP sites are listed in URL format, as shown below:
protocol://site.name/
protocol://site.name/directory/
protocol://site.name/directory/file.name

`BYTE`	8-bit unsigned data
`CHAR`	8-bit signed data
`WORD`	16-bit unsigned integer
`SHORT`	16-bit signed integer
`DWORD`	32-bit unsigned integer
`LONG`	32-bit signed integer
`FLOAT`	32-bit single-precision floating point number
`DOUBLE`	64-bit double-precision floating point number
