Tom,
The reason this code is not just using dlopen with a library name is that the
_eglPreloadDisplayDrivers function is attempting to find all driver libraries
that match a pattern such as "egl_x11_*.so". Any one of those libraries might
be the best one to use. It loads them all and uses a "Probe" function
in each driver to look for the best match for the hardware.
dlopen itself cannot find libraries that match a pattern.
