CURLOPT_FTPSSLAUTH - order in which to attempt TLS vs SSL
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTPSSLAUTH, long order);
Pass a long using one of the values from below, to alter how libcurl issues "AUTH TLS" or "AUTH SSL" when FTP over SSL is activated. This is only interesting if CURLOPT_USE_SSL(3) is also set.
Possible order values:
CURLFTPAUTH_DEFAULT
FTP
int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/file.txt"); curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_TRY); /* funny server, ask for SSL before TLS */ curl_easy_setopt(curl, CURLOPT_FTPSSLAUTH, (long)CURLFTPAUTH_SSL); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } }
Added in 7.12.2
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
