SDL_CopyProperties - Man Page

#include <SDL3/SDL_properties.h>

bool SDL_CopyProperties(SDL_PropertiesID src, SDL_PropertiesID dst);

Copy all the properties from one group of properties to another, with the exception of properties requiring cleanup (set using SDL_SetPointerPropertyWithCleanup()), which will not be copied. Any property that already exists on dst will be overwritten.

src

the properties to copy.

dst

the destination properties.

Returns true on success or false on failure; call SDL_GetError() for more information.

It is safe to call this function from any thread. This function acquires simultaneous mutex locks on both the source and destination property sets.

This function is available since SDL 3.2.0.
