CURLINFO_CAINFO(3) Library Functions Manual CURLINFO_CAINFO(3)
NAME
CURLINFO_CAINFO - get the default built-in CA certificate path
SYNOPSIS
#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.
PROTOCOLS
This functionality affects all TLS based protocols: HTTPS, FTPS, IMAPS,
POP3S, SMTPS etc.
All TLS backends support this option.
EXAMPLE
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 curl 7.84.0
