NAME

       CURLINFO_CAINFO - get the default built-in CA certificate path

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAINFO, char **path);

DESCRIPTION

       Pass  a  pointer  to  a  char  pointer  to receive the pointer to a null-terminated string
       holding the default built-in path used for the CURLOPT_CAINFO(3) option unless set by  the
       user.

       Note  that  in a situation where libcurl has been built to support multiple TLS libraries,
       this option might return a string even if the specific TLS library  currently  set  to  be
       used does not support CURLOPT_CAINFO(3).

       This is a path identifying a single file containing CA certificates.

       The path pointer is set to NULL if there is no default path.

PROTOCOLS

       This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

       All TLS backends support this option.

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           char *cainfo = NULL;
           curl_easy_getinfo(curl, CURLINFO_CAINFO, &cainfo);
           if(cainfo) {
             printf("default ca info path: %s\n", cainfo);
           }
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 7.84.0

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
