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.

EXAMPLE

    if(cainfo) {
      printf("default ca info path: %s\n", cainfo);
    }
    curl_easy_cleanup(curl);
  }
}
