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 an 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 age of this struct this is. The  number  depends  on
       how  new	 libcurl  you're  using.  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 extra debug capabilities built-in.
		     This is mainly of interest for libcurl hackers. (added in

		     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 CUURLOPT_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.
