Function Documentation

blo_do_versions_dna()

void blo_do_versions_dna	(	SDNA *	sdna,
		int	versionfile,
		int	subversionfile )

Manipulates SDNA before calling DNA_struct_get_compareflags, allowing us to rename structs and struct members.

• This means older versions of Blender won't have access to this data USE WITH CARE.
• These changes are applied on file load (run-time), similar to versioning for compatibility.

Attention

ONLY USE THIS KIND OF VERSIONING WHEN dna_rename_defs.h ISN'T SUFFICIENT.
