# NAME
|
||
|
|
|
||
|
|
CURLINFO_SCHEME - get the URL scheme (sometimes called protocol) used in the connection
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SCHEME, char **scheme);
|
||
|
|
~~~
|
||
|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a pointer to a char pointer to receive the pointer to a null-terminated
|
||
|
|
string holding the URL scheme used for the most recent connection done with
|
||
|
|
this CURL **handle**.
|
||
|
|
|
||
|
|
The **scheme** pointer is NULL or points to private memory. You MUST NOT
|
||
|
|
free - it gets freed when you call curl_easy_cleanup(3) on the
|
||
|
|
corresponding CURL handle.
