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

curl_easy_getinfo(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
