Conventions
The following conventions appear in this document:
» The » symbol leads you through nested menu items and dialog box options
to a final action. The sequence File»Page Setup»Options directs you to
pull down the File menu, select the Page Setup item, and select Options
from the last dialog box.
This icon denotes a note, which alerts you to important information.
bold Bold text denotes items that you must select or click in the software, such
as menu items and dialog box options. Bold text also denotes parameter
names and hardware labels.
italic Italic text denotes variables, emphasis, a cross-reference, or an introduction
to a key concept. Italic text also denotes text that is a placeholder for a word
or value that you must supply.
monospace
Monospace text denotes text or characters that you should enter from the
keyboard, sections of code, programming examples, and syntax examples.
This font is also used for the proper names of disk drives, paths, directories,
programs, subprograms, subroutines, device names, functions, operations,
variables, filenames, and extensions.
ReturnValue A parameter which points to data that is modified by a function call has a
variable name in the form <variableTypeReturnValue>, for example,
uInt32PointerReturnValue
. All function calls return a status integer
that you must verify. Because all the functions return this status integer, the
function descriptions in this document omit the status integer.
Number Variable Types The integer variable type used in this document is represented as a whole
number. Any floating point variable type is represented as a number with a
decimal point. For example, the number 1,024 is written as
1024
if it is an
integer, and as
1024.0
if it is a floating point value.
