Function khronos_egl::choose_config

pub fn choose_config(
    display: Display, 
    attrib_list: &[Int], 
    configs: &mut Vec<Config>
) -> Result<(), Error>

Return a list of EGL frame buffer configurations that match specified attributes.

This will write as many matching configurations in configs up to its capacity. You can use the function matching_config_count to get the exact number of configurations matching the specified attributes.

Example

// Get the number of matching configurations.
let count = egl::matching_config_count(display, &attrib_list)?;

// Get the matching configurations.
let mut configs = Vec::with_capacity(count);
egl::choose_config(display, &attrib_list, &mut configs)?;

This will return a BadParameter error if attrib_list is not a valid attributes list (if it does not terminate with NONE).
