The igraph library. (download) This library offers basic facilities to convert Lua values to and from C structs.
Its main functions are struct.pack, which packs multiple Lua values into a struct-like string; and struct.unpack, which unpacks multiple Lua values from a given struct-like string. The fist argument to both functions is a format string, which describes the layout of the structure. The format string is a sequence of conversion elements, which respect the current endianess and the current alignment requirements. Welcome to Hama project.
