I tried to use libcurl with cffi.
It's fine in luajit. but with puc it give error
libc: Fatal signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x7ac9a706e0 in tid 27717 (lua), pid 27717 (lua)
the problem is when doing curl_callback.
Also without this line in luajit also give strange incomplete result. maybe it's important to redefine the built-in typedefs which cffi fail to compile.
typedef int64_t time_t;
typedef unsigned int size_t;
local curl = require("libcurl-ffi")
-- local curl = require("luajit-curl")
local ffi = require"ffi" or require"cffi"
local ch = curl.curl_easy_init()
function curl_callback(callfunc)
return ffi.cast("curl_callback", function (ptr, size, nmemb, stream)
local bytes = size*nmemb
local dst = ffi.new("char[?]", size*nmemb)
ffi.copy(dst, ptr, size*nmemb)
callfunc(ffi.string(dst, size*nmemb))
return bytes
end)
end
if (ch) then
curl.curl_easy_setopt(ch, curl.CURLOPT_URL, "http://example.com")
curl.curl_easy_setopt(ch, curl.CURLOPT_FOLLOWLOCATION, 1)
local raw_body = {}
local raw_header = {}
local clb_write = curl_callback(function(s) table.insert(raw_body, s) end)
local clb_header = curl_callback(function(s) table.insert(raw_header, s) end)
curl.curl_easy_setopt(ch, curl.CURLOPT_WRITEFUNCTION, clb_write)
curl.curl_easy_setopt(ch, curl.CURLOPT_HEADERFUNCTION, clb_header)
local success, err = pcall(function()
return curl.curl_easy_perform(ch)
end)
clb_write:free()
clb_header:free()
print(success, err)
-- local result = curl.curl_easy_perform(ch)
-- if (result ~= curl.CURLE_OK) then

if #raw_header>0 then
print(table.concat(raw_header))
