CURLINFO_CAINFO - get the default built-in CA certificate path

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAINFO, char **path);

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.

All

CURL *curl = curl_easy_init();
if(curl) {

CURLcode res;
char *cainfo = NULL;
curl_easy_getinfo(curl, CURLINFO_CAINFO, &cainfo);
if(cainfo)
printf("default ca info path: %s\n", cainfo);
}
curl_easy_cleanup(curl); }

Added in 7.84.0

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