CURLINFO_CAPATH explained

Name

CURLINFO_CAPATH - get the default built-in CA path string

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAPATH, 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_CAPATH 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_CAPATH.

This is a path identifying a directory.

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.

This option works only with the following TLS backends: GnuTLS, OpenSSL, mbedTLS and wolfSSL

Example

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    char *capath = NULL;
    curl_easy_getinfo(curl, CURLINFO_CAPATH, &capath);
    if(capath) {
      printf("default ca path: %s\n", capath);
    }
    curl_easy_cleanup(curl);
  }
}

Availability

Added in curl 7.84.0

Return value

curl_easy_getinfo returns a CURLcode indicating success or error.

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