- .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
