Get a property on a set of properties
void* SDL_GetProperty(SDL_PropertiesID props, const char *name, void *default_value);
|props||the properties to query|
|name||the name of the property to query|
|default_value||the default value of the property|
Returns the value of the property, or
default_value if it is not set or not a pointer property.
By convention, the names of properties that SDL exposes on objects will start with "SDL.", and properties that SDL uses internally will start with "SDL.internal.". These should be considered read-only and should not be modified by applications.
It is safe to call this function from any thread, although the data returned is not protected and could potentially be freed if you call SDL_SetProperty() or SDL_ClearProperty() on these properties from another thread. If you need to avoid this, use SDL_LockProperties() and SDL_UnlockProperties().
This function is available since SDL 3.0.0.
