The short descriptions describe the data each info retrieves. The info itself does not 'get' the data. This simplifies and shortens the descriptions and make them more consistent. Closes #19406

# NAME
|
|
|
|
CURLINFO_CAINFO - 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);
|
|
}
