By supporting pathname space mapping, by having a well-defined interface to resource managers, and by providing a set of libraries for common resource manager functions, the QNX Neutrino RTOS offers the developer unprecedented flexibility and simplicity in developing “drivers” for new hardware—a critical feature for many embedded systems.
For more details on developing a resource manager, see the Resource Managers chapter of Getting Started with QNX Neutrino, and the Writing a Resource Manager guide.
