LibCURL.jl

Julia wrapper for libCURL

This is a simple Julia wrapper around http://curl.haxx.se/libcurl/ generated using Clang.jl.

Example (fetch a URL)

using LibCURL

# init a curl handle
curl = curl_easy_init()

# set the URL and request to follow redirects
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com")
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1)


# setup the callback function to recv data
function curl_write_cb(curlbuf::Ptr{Void}, s::Csize_t, n::Csize_t, p_ctxt::Ptr{Void})
    sz = s * n
    data = Array{UInt8}(sz)
    
    ccall(:memcpy, Ptr{Void}, (Ptr{Void}, Ptr{Void}, UInt64), data, curlbuf, sz)
    println("recd: ", String(data))
    
    sz::Csize_t
end

c_curl_write_cb = cfunction(curl_write_cb, Csize_t, (Ptr{Void}, Csize_t, Csize_t, Ptr{Void}))
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, c_curl_write_cb)


# execute the query
res = curl_easy_perform(curl)
println("curl url exec response : ", res)

# retrieve HTTP code
http_code = Array{Clong}(1)
curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, http_code)
println("httpcode : ", http_code)

# release handle
curl_easy_cleanup(curl)
