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 will be NULL if there is no default path.

PROTOCOLS
All

EXAMPLE
CURL *curl = curl_easy_init();

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

AVAILABILITY
