curl_version_info(3)		libcurl Manual		  curl_version_info(3)

       curl_version_info - returns run-time libcurl version info

       #include <curl/curl.h>

       curl_version_info_data *curl_version_info( CURLversion type);

       Returns	a pointer to a filled in struct with information about various
       run-time features in libcurl. type should be set to the version of this
       functionality  by  the  time  you write your program. This way, libcurl
       will always return a proper struct that your program understands, while
       programs	 in  the  future might get a different struct. CURLVERSION_NOW
       will be the most recent one for the library you have installed:

	       data = curl_version_info(CURLVERSION_NOW);

       Applications should use this information to judge if things are	possi‐
       ble  to do or not, instead of using compile-time checks, as dynamic/DLL
       libraries can be changed independent of applications.

       The curl_version_info_data struct looks like this

       typedef struct {
	 CURLversion age;	   /* see description below */

	 /* when 'age' is 0 or higher, the members below also exist: */
	 const char *version;	   /* human readable string */
	 unsigned int version_num; /* numeric representation */
	 const char *host;	   /* human readable string */
	 int features;		   /* bitmask, see below */
	 char *ssl_version;	   /* human readable string */
	 long ssl_version_num;	   /* not used, always zero */
	 const char *libz_version; /* human readable string */
	 const char **protocols;   /* list of protocols */

	 /* when 'age' is 1 or higher, the members below also exist: */
	 const char *ares;	   /* human readable string */
	 int ares_num;		   /* number */

	 /* when 'age' is 2 or higher, the member below also exists: */
	 const char *libidn;	   /* human readable string */

	 /* when 'age' is 3 or higher, the members below also exist: */
	 int iconv_ver_num;	  /* '_libiconv_version' if iconv support enabled */

	 const char *libssh_version; /* human readable string */

       } curl_version_info_data;

       age describes what the age of this struct is. The number depends on how
       new  the	 libcurl  you're using is. You are however guaranteed to get a
       struct that you have a matching struct for in the header, as  you  tell
       libcurl your "age" with the input argument.

       version is just an ascii string for the libcurl version.

       version_num is a 24 bit number created like this: <8 bits major number>
       | <8 bits minor number> | <8  bits  patch  number>.  Version  7.9.8  is
       therefore returned as 0x070908.

       host is an ascii string showing what host information that this libcurl
       was built for. As discovered by a configure script or set by the	 build

       features can have none, one or more bits set, and the currently defined
       bits are:

		     supports IPv6

		     supports kerberos4 (when using FTP)

		     supports SSL (HTTPS/FTPS) (Added in 7.10)

		     supports HTTP deflate using libz (Added in 7.10)

		     supports HTTP NTLM (added in 7.10.6)

		     supports HTTP GSS-Negotiate (added in 7.10.6)

		     libcurl was  built	 with  debug  capabilities  (added  in

		     libcurl  was  built  with memory tracking debug capabili‐
		     ties. This is mainly of  interest	for  libcurl  hackers.
		     (added in 7.19.6)

		     libcurl  was  built  with	support	 for asynchronous name
		     lookups, which allows more exact timeouts (even  on  Win‐
		     dows)  and	 less blocking when using the multi interface.
		     (added in 7.10.7)

		     libcurl was built with support for SPNEGO	authentication
		     (Simple  and  Protected  GSS-API  Negotiation  Mechanism,
		     defined in RFC 2478.) (added in 7.10.8)

		     libcurl was built with support for large files. (Added in

		     libcurl  was  built  with	support for IDNA, domain names
		     with international letters. (Added in 7.12.0)

		     libcurl was built with support for	 SSPI.	This  is  only
		     available	on  Windows and makes libcurl use Windows-pro‐
		     vided functions for NTLM authentication. It  also	allows
		     libcurl  to  use  the current user and the current user's
		     password without the app having to pass them  on.	(Added
		     in 7.13.2)

		     libcurl was built with support for character conversions,
		     as provided by the CURLOPT_CONV_*	callbacks.  (Added  in
       ssl_version is an ASCII string for the OpenSSL version used. If libcurl
       has no SSL support, this is NULL.

       ssl_version_num is the numerical OpenSSL version value  as  defined  by
       the OpenSSL project. If libcurl has no SSL support, this is 0.

       libz_version  is	 an  ASCII  string (there is no numerical version). If
       libcurl has no libz support, this is NULL.

       protocols is a pointer to an array of char * pointers,  containing  the
       names  protocols	 that  libcurl supports (using lowercase letters). The
       protocol names are the same as would be used in URLs. The array is ter‐
       minated by a NULL entry.
