Enumeration Type Documentation

anonymous enum

anonymous enum

Codes used for BHead.code.

These coexist with ID codes such as ID_OB, ID_SCE ... etc.

Enumerator
BLO_CODE_DATA	Arbitrary allocated memory (typically owned by ID's, will be freed when there are no users).
BLO_CODE_GLOB	Used for Global struct.
BLO_CODE_DNA1	Used for storing the encoded SDNA string (decoded into an SDNA on load).
BLO_CODE_TEST	Used to store thumbnail previews, written between #REND and #GLOB blocks, (ignored for regular file reading).
BLO_CODE_REND	Used for RenderInfo, basic Scene and frame range info, can be easily read by other applications without writing a full blend file parser.
BLO_CODE_USER	Used for UserDef, (user-preferences data). (written to BLENDER_STARTUP_FILE & BLENDER_USERPREF_FILE).
BLO_CODE_ENDB	Terminate reading (no data).
