void light_copy_data ( Main * bmain, std::optional< Library * > owner_library, ID * id_dst, const ID * id_src, const int flag )

Only copy internal data of Light ID from source to already allocated/initialized destination. You probably never want to use that directly, use BKE_id_copy or BKE_id_copy_ex for typical needs.

WARNING! This function will not handle ID user count!

Parameters

flag	Copying options (see BKE_lib_id.hh's LIB_ID_COPY_... flags for more).
