Working with External APIs

Applications communicate with the QNX Composition manager through open, standard APIs. For more information, refer to the third-party documentation for each API:

OpenKODE

http://www.khronos.org/openkode/

OpenKODE is a royalty-free open standard that increases the source portability of media and graphics applications.

OpenKODE 1.0.2 libraries on QNX Neutrino

Location Name File
/usr/lib libKD.so.1 <Core KD/kd.h>
Note: Note that only a subset of OpenKODE revision 1.0.2 is provided to interface with the QNX Composition Manager. This subset includes chapters: 5-Error, 7- Threads, 8-Events, 10-Application startup and exit, 21-Input/output, and 22-Windowing. The complete list of OpenKODE functions provided with libKD.so can be found at the end of this section.

This implementation also includes some QNX extensions. The KD_QNX_window extension supplements the core windowing specification with additional window properties and events. The KD_QNX_input extension adds support for keyboards and assignment of focus on a per I/O group basis.

EGL

http://www.khronos.org/egl/

EGL is an interface between Khronos rendering APIs and the underlying native platform windowing system. The implementation of EGL 1.4 provided in this release isn't compatible with previous versions of EGL 1.2 supplied with Advanced Graphics. The display_id argument to eglGetDisplay() is a numeric identifier, rather than a gf_device_t handle, and the EGL_DEFAULT_DISPLAY constant is now an accepted value. Both implementations will continue to be distributed to allow existing applications to compile and run once the QNX Neutrino has been installed. Legacy applications will get EGL 1.2 entry points from OpenGL ES 1.0 libraries, and new and updated applications must link against libEGL.so to get the new entry points. Note that only the new EGL 1.4 supports connections to the Composition Manager.
