+# NAME
+
+curl_version - returns the libcurl version string
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+char *curl_version();
+~~~
+
+# DESCRIPTION
+
+Returns a human readable string with the version number of libcurl and some of
+its important components (like OpenSSL version).
+
+For MultiSSL builds the string contains all SSL backend names and the inactive
+backend names are in parentheses. For example "(OpenSSL/3.0.8) Schannel" or
+"OpenSSL/3.0.8 (Schannel)".
+
+We recommend using curl_version_info(3) instead.
