Hi,
I have observed that when opensocket_callback returns CURL_SOCKET_BAD,
libcurl returns CURLE_FAILED_INIT instead of CURLE_COULDNT_CONNECT. This
is incorrect as per the documentation at
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTOPENSOCKETFUNCTION.
Is this a bug?
This can be easily reproduced by changing the return value of opensocket
function to CURL_SOCKET_BAD, in the example program externalsocket.c.
When I executed with this change I got the below output,
$./a.out
* About to connect() to 99.99.99.99 port 9999 (#0)
* Closing connection #0
* Failed initialization
libcurl error: 2
and my change was,
--- externalsocket.c.orig 2012-03-25 14:48:53.505770709 +0400
+++ externalsocket.c 2012-03-25 14:30:25.017793554 +0400
