CURLINFO_CAINFO(3)         Library Functions Manual         CURLINFO_CAINFO(3)

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
       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 7.84.0

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