creator of the requested OpenMAX component
creator of the requested openmax component
This function searches for the requested component in the internal list. If the component is found, its constructor is called, and the standard callbacks are assigned. A pointer to a standard OpenMAX component is returned.

the ST static loader contructor
The constructor of the ST specific component loader.
This function creates the ST static component loader, and creates the list of available components, based on a registry file created by a separate appication. It is called omxregister, and must be called before the use of this loader

This pointer holds and handle allocate by this loader and requested by some application. If the IL client does not de-allocate it calling explicitely the FreeHandle function, any pending handle is release at the end, when the global function OMX_Deinit is called. This list takes track of any handle
