SDL_SetPointerPropertyWithCleanup - Man Page

#include <SDL3/SDL_properties.h>

bool SDL_SetPointerPropertyWithCleanup(SDL_PropertiesID props, const char *name, void *value, SDL_CleanupPropertyCallback cleanup, void *userdata);

The cleanup function is also called if setting the property fails for any reason.

For simply setting basic data types, like numbers, bools, or strings, use SDL_SetNumberProperty, SDL_SetBooleanProperty, or SDL_SetStringProperty instead, as those functions will handle cleanup on your behalf. This function is only for more complex, custom data.

props

the properties to modify.

name

the name of the property to modify.

value

the new value of the property, or NULL to delete the property.

cleanup

the function to call when this property is deleted, or NULL if no cleanup is necessary.

userdata

a pointer that is passed to the cleanup function.

for more information.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
