Wow, this is such cool stuff :)
I've got a question about the intended behaviour of VLA's, though.
What's the canonical way to resize them? I don't get the "Variable
Length" part of "Variable Length Array". Do we use ffi.C.realloc and
friends, or is it smarter than that?
The following segfaults on my box:
local ffi = require("ffi")
ffi.cdef[[
int sprintf(char *str, const char *format, ...);
]]
local buf = ffi.new("char[?]", 16)
ffi.C.sprintf(buf, "%s", string.rep("x", 17)) -- buffer overflow?
print(ffi.string(buf));
Grateful for any pointers (excuse the pun).
Thanks,
Richard
