About this Reference

The MME Developer's Guide accompanies the QNX Aviage multimedia suite. It is intended for application developers who use the suite's MultiMedia Engine (MME) to develop multimedia applications.

Note that the MME is a component of the QNX Aviage multimedia core package, which is available in the QNX Aviage multimedia suite of products. The MME is the main component of this core package. It is used for configuration and control of your multimedia applications.

Typographical conventions

Throughout this manual, we use certain typographical conventions to distinguish technical terms. In general, the conventions we use conform to those found in IEEE POSIX publications. The following table summarizes our conventions:

Reference Example
Code examples if( stream == NULL )
Command options -lR
Commands make
Environment variables PATH
File and pathnames /dev/null
Function names exit()
Keyboard chords Ctrl-Alt-Delete
Keyboard input something you type
Keyboard keys Enter
Program output login:
Programming constants NULL
Programming data types unsigned short
Programming literals 0xFF, "message string"
Variable names stdin
User-interface components Cancel

We use an arrow (→) in directions for accessing menu items, like this:

You'll find the Other... menu item under Perspective-->Show View.

We use notes, cautions, and warnings to highlight important messages:


Note: Notes point out something important or useful.


Caution: Cautions tell you about commands or procedures that may have unwanted or undesirable side effects.


WARNING: Warnings tell you about commands or procedures that could be dangerous to your files, your hardware, or even yourself.

Note to Windows users

In our documentation, we use a forward slash (/) as a delimiter in all pathnames, including those pointing to Windows files.

We also generally follow POSIX/UNIX filesystem conventions.

Navigation buttons

At the top and bottom of our HTML docs, you'll see some or all of these buttons:
