.SH NAME
CURLINFO_CAINFO \- get the default built\-in CA certificate path
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CAINFO, char **path);
.fi
.SH 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 \fICURLOPT_CAINFO(3)\fP
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 \fICURLOPT_CAINFO(3)\fP.

This is a path identifying a single file containing CA certificates.

The \fBpath\fP pointer is set to NULL if there is no default path.
.SH PROTOCOLS
This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

All TLS backends support this option.
.SH EXAMPLE
.nf
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);
  }
}
.fi
.SH AVAILABILITY
Added in curl 7.84.0
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
