           Summary: Wrong curl onProgress examples
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1

https://dlang.org/phobos/std_net_curl.html#.HTTP.onProgress

The example fails to compile because the mismatch ult <-> uln and also the
return 0 statement is missing.

import std.net.curl, std.stdio;
auto client = HTTP("dlang.org");
client.onProgress = delegate int(size_t dl, size_t dln, size_t ul, size_t ult)
{
    writeln("Progress: downloaded ", dln, " of ", dl);
    writeln("Progress: uploaded ", uln, " of ", ul);
};
client.perform();


https://dlang.org/phobos/std_net_curl.html#.Curl.onProgress
Also this example is wrong and parameters block looks not properly formatted.
curl.perform should be outside the delegate. return 0 is missing. mismatch uln
<-> ulnow

import std.net.curl;
Curl curl;
curl.initialize();
curl.set(CurlOption.url, "http://dlang.org");
curl.onProgress = delegate int(size_t dltotal, size_t dlnow, size_t ultotal,
size_t uln)
{
    writeln("Progress: downloaded bytes ", dlnow, " of ", dltotal);
    writeln("Progress: uploaded bytes ", ulnow, " of ", ultotal);
    curl.perform();
};
