[Bf-committers] SDNA code and starting Python scripts from command line

[Ton Roosendaal]

Hi,

1. There's a sort-of python board now. They can review it. I wouldn't =20=

consider this a showstopper though... nice to put at the list to do!

2. In blender/source/blender/blenkernel/intern/blender.c there's a line =20=

setting global variable G.order. That's how the system's endianess is =20=

defined.
In each file there's a code for the endianness too. It's a hack: the =20
'magic number' of a file has info hidden in it:

BLENDER-V220
        ^     a '-' is 32 bits, a '_' is 64 bits files
         ^    a 'V' is big endian, a 'v' is little endian

-Ton-


in file blender/source/blender/blenloader/intern/readfile.c function =20
decode_blender_header is the code.
