I have looked at http://lua-users.org/wiki/StructurePacking
Ihave tried vstruct ( works, but only read into a table(array), no
dictionary)
lunary it looks like it read into table but can not get it to work,
stream problem I think
It would be easier for me to write a C function and return a dictionary(
C background)
The documentation for vstruct could be much better, start with a very
simple working example
#!/usr/bin/env lua
require "vstruct"
require "serial"
local f = assert(io.open("SAVE10.GAM","rb"))
local sz = f:seek("end")
f:seek("set")
local stream = serial.filestream(f)
local block = 100
local data = "" block)
local fmt = "i4 s27 i4 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1
i1 i1 i1 i1 i1 i1 i1 i1 i1"
local lfmt = {
{ "version", uint32},
{ "desc", cstring},
{ "gamtyp", uint8}
}
print ( type( lfmt), type(stream), stream, lfmt)
local out = vstruct.unpack(fmt,data)
f:seek("set")
local out2 = serial.read.struct(stream,lfmt) *****
for k,v in pairs(out2) do
print( k,v)
end
