Question

I am attempting to write an application that uses libCurl to post soap requests to a secure web service. This Windows application is built against libCurl version 7.19.0 which, in turn, is built against openssl-0.9.8i. The pertinent curl related code follows:

 FILE *input_file = fopen(current->post_file_name.c_str(), 'rb'); FILE *output_file = fopen(current->results_file_name.c_str(), 'wb'); if(input_file && output_file) {     struct curl_slist *header_opts = 0;     CURLcode rcd;      header_opts = curl_slist_append(header_opts, 'Content-Type: application/soap+xml; charset=utf8');     curl_easy_reset(curl_handle);     curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1);     curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, output_file);     curl_easy_setopt(curl_handle, CURLOPT_READDATA, input_file);     curl_easy_setopt(curl_handle, CURLOPT_URL, fs_service_url);     curl_easy_setopt(curl_handle, CURLOPT_POST, 1);     curl_easy_setopt(curl_handle, CURLOPT_HTTPHEADER, header_opts);     rcd = curl_easy_perform(curl_handle);     if(rcd != 0)     {         current->curl_result = rcd;         current->curl_error = curl_easy_strerror(rcd);     }     curl_slist_free_all(header_opts); } 

When I attempt to execute the URL, curl returns an CURLE_OUT_OF_MEMORY error which appears to be related to a failure to allocate an SSL context. Has anyone else encountered this problem before?

Answer 1

After further investigation, I found that this error was due to a failure to initialise the openSSL library by calling SSL_library_init().
