SDL_SetPointerPropertyWithCleanup - Man Page
Set a pointer property in a group of properties with a cleanup function that is called when the property is deleted.
Synopsis
#include <SDL3/SDL_properties.h> bool SDL_SetPointerPropertyWithCleanup(SDL_PropertiesID props, const char *name, void *value, SDL_CleanupPropertyCallback cleanup, void *userdata);
Description
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.
Function Parameters
- 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.
Return Value
Returns true on success or false on failure; call SDL_GetError() for more information.
Thread Safety
It is safe to call this function from any thread.
Availability
This function is available since SDL 3.2.0.
