Type Alias SDL_EnumeratePropertiesCallback 

pub type SDL_EnumeratePropertiesCallback = Option<unsafe extern "C" fn(userdata: *mut c_void, props: SDL_PropertiesID, name: *const c_char)>;

A callback used to enumerate all the properties in a group of properties.

This callback is called from SDL_EnumerateProperties(), and is called once per property in the set.

Parameter: userdata an app-defined pointer passed to the callback. Parameter: props the SDL_PropertiesID that is being enumerated. Parameter: name the next property name in the enumeration.

Thread Safety: SDL_EnumerateProperties holds a lock on props during this callback.

Available Since: This datatype is available since SDL 3.2.0.
