CURLINFO_CAPATH(3) Library Functions Manual CURLINFO_CAPATH(3)

CURLINFO_CAPATH - get the default built-in CA path string

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAPATH, 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_CAPATH(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_CAPATH(3).

This is a path identifying a directory.

The path pointer is set to NULL if there is no default path.

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

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

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);

Added in 7.84.0

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