[Bf-committers] Blender with 64bit blendfile

[Jaros Milan]

Hi Sergey,


I know about SDNA and its types. I mean for example in writefile.c this functions: writedata* and writestruct*. They have int len/nr.


Thanks.

Milan

HI,

size_t type is platform-specific and needs special handling in SDNA code.
So you can't just put it to DNA and hope it works.

What you should be doing instead is to use platform-independent 64 bit type
which is int64_t/uint64_t and which is already supported for ages.
