Examples and program code appear in a non-proportional typeface. |
| Bold text | Literal expressions that must be typed exactly as shown, such as function names, structure names, and keywords, appear in this bold typeface. |
| Italic text | Italic text indicates new terms and variable expressions, such as parameters, where you fill in the actual value. |
| CAPITAL LETTERS | Filenames, directory names, paths, function flags, and error messages appear in capital letters. |
| ( ) | In syntax statements, parentheses enclose one or more parameters that you pass to a function. |
| [ ] | Brackets enclose optional syntax items. Type only the syntax within the brackets, not the brackets themselves. |
