# NAME
CURLINFO_CAINFO - get the default built-in CA certificate path
# SYNOPSIS
~~~c
#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.
# EXAMPLE
~~~c
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 7.84.0
# RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
