sdlLoadPngIo function surface

Pointer<SdlSurface> sdlLoadPngIo(Pointer<SdlIoStream> src, bool closeio)

Load a PNG image from a seekable SDL data stream.

The new surface should be freed with SDL_DestroySurface(). Not doing so will result in a memory leak.

\param src the data stream for the surface. \param closeio if true, calls SDL_CloseIO() on src before returning, even in the case of an error. \returns a pointer to a new SDL_Surface structure or NULL on failure; call SDL_GetError() for more information.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.4.0.
