EGLint rcChooseConfig(EGLint *attribs, uint32_t attribs_size, uint32_t *configs, uint32_t configs_size)
This function triggers an eglChooseConfig on the host, to get a list of
configs matching the given attribs values.
attribs - a list of attribute names followed by the desired values, terminated by EGL_NONE
attribs_size - the size of the list
configs - the returned matching configuration names (same names as familiar to the client in rcGetConfigs)
configs_size - the size of the configs buffers
returns - the actual number of matching configurations (<= configs_size)
EGLint rcGetFBParam(EGLint param);
queries the host for framebuffer parameter, see renderControl_types.h
for possible values of 'param'.
