Check if file exist for form curl.

[jbeitz107]

I want to simply see if a file exists so that it will add another formadd for CURL in C++. Any help would be appreciated. Here is my code so far but, need help.

CURL *curl;

    struct curl_httppost *formpost = NULL;
    struct curl_httppost *lastptr = NULL;

    curl_global_init(CURL_GLOBAL_ALL);

	curl_formadd(&formpost,
        &lastptr,
        CURLFORM_COPYNAME, "image",
        CURLFORM_FILE, "1stfile.txt",
        CURLFORM_END);

	if(ifstream("2ndfile.txt")){
	curl_formadd(&formpost,
        &lastptr,
        CURLFORM_COPYNAME, "image",
        CURLFORM_FILE, "2ndfile.txt",
        CURLFORM_END);
	}
	curl_formadd(&formpost,
        &lastptr,
        CURLFORM_COPYNAME, "submit",
        CURLFORM_COPYCONTENTS, "submit",
		CURLFORM_END);

	
    curl = curl_easy_init();
