/*
FILEFORMAT: IFF-style structure (but not IFF compatible!)
start file:
BLENDER_V100 12 bytes (versie 1.00)
V = big endian, v = little endian
_ = 4 byte pointer, - = 8 byte pointer
datablocks: also see struct BHead
<bh.code> 4 chars
<bh.len> int, len data after BHead
<bh.old> void, old pointer
<bh.SDNAnr> int
<bh.nr> int, in case of array: amount of structs
data
...
...
Almost all data in Blender are structures. Each struct saved
gets a BHead header. With BHead the struct can be linked again
and compared with StructDNA .
WRITE
Preferred writing order: (not really a must, but why would you do it random?)
Any case: direct data is ALWAYS after the lib block
(Local file data)
- for each LibBlock
- write LibBlock
- write associated direct data
(External file data)
- per library
- write library block
- per LibBlock
- write the ID of LibBlock
- write FileGlobal (some global vars)
- write SDNA
- write USER if filename is ~/.B.blend
