Add .nf and .fi such that the code gets wrapped in a pre on the web.
Fixed grammar, fixed formatting of the "See also" items.

 Given that you have an nginx server running, listening on /tmp/nginx.sock, you
 can request a HTTP resource with:
 
+.nf

     curl_easy_setopt(curl_handle, CURLOPT_URL, "http://localhost/");

 If you are on Linux and somehow have a need for paths larger than 107 bytes, you
 could use the proc filesystem to bypass the limitation:
 
+.nf
     int dirfd = open(long_directory_path_to_socket, O_DIRECTORY | O_RDONLY);
     char path[108];
     snprintf(path, sizeof(path), "/proc/self/fd/%d/nginx.sock", dirfd);
