Detailed Description

Struct muncher for making SDNA.

About makesdna tool

Originally by Ton, some mods by Frank, and some cleaning and extension by Nzc.

Makesdna creates a .c file with a long string of numbers that encode the Blender file format. It is fast, because it is basically a binary dump. There are some details to mind when reconstructing the file (endianness and byte-alignment).

This little program scans all structs that need to be serialized, and determined the names and types of all members. It calculates how much memory (on disk or in ram) is needed to store that struct, and the offsets for reaching a particular one.

There is a facility to get verbose output from sdna. Search for debugSDNA. This int can be set to 0 (no output) to some int. Higher numbers give more output.

Function Documentation

int add_name ( char * str )

Add variable str to

Parameters:

str	Because of the weird way of tokenizing, we have to 'cast' function pointers to ... (*f)(), whatever the original signature. In fact, we add name and type at the same time... There are two special cases, unfortunately. These are explicitly checked.

short * add_struct ( int namecode )

Search whether this structure type was already found, and if not, add it.
