#inclib "curl"

/' This is the global package copyright '/
#define LIBCURL_COPYRIGHT "1996 - 2011 Daniel Stenberg, <daniel@haxx.se>."

/' This is the version number of the libcurl package from which this header
   file origins: '/
#define LIBCURL_VERSION "7.24.0"

/' The numeric version number is also available "in parts" by using these
   defines: '/
#define LIBCURL_VERSION_MAJOR 7
#define LIBCURL_VERSION_MINOR 24
#define LIBCURL_VERSION_PATCH 0

/' This is the numeric version of the libcurl version number, meant for easier
   parsing and comparions by programs. The LIBCURL_VERSION_NUM define will
   always follow this syntax:

         0xXXYYZZ

   Where XX, YY and ZZ are the main version, release and patch numbers in
   hexadecimal (using 8 bits each). All three numbers are always represented
   using two digits.  1.2 would appear as "0x010200" while version 9.11.7
   appears as "0x090b07".

   This 6-digit (24 bits) hexadecimal number does not show pre-release number,
   and it is always a greater number in a more recent release. It makes
   comparisons with greater than and less than work.

 * This is the date and time when the full source package was created. The

  *          argument's integer-pointer.

  * Returns: CURLMcode type, general multi error code. *NOTE* that this only

  * Name:    curl_multi_cleanup()

  *          in what state those handles will be if this function is called
  *          in the middle of a transfer.

  * Returns: CURLMcode type, general multi error code.

declare function curl_multi_cleanup(byval multi_handle as CURLM ptr) as CURLMcode

/'
 * Name:    curl_multi_info_read()
 *
 * Desc:    Ask the multi handle if there's any messages/informationals from
 *          the individual transfers. Messages include informationals such as
 *          error code from the transfer or just the fact that a transfer is
 *          completed. More details on these should be written down as well.
 *
 *          Repeated calls to this function will return a new struct each
 *          time, until a special "end of msgs" struct is returned as a signal
 *          that there is no more to get at this point.
 *
 *          The data the returned pointer points to will not survive calling
 *          curl_multi_cleanup().
 *
 *          The 'CURLMsg' struct is meant to be very simple and only contain
 *          very basic informations. If more involved information is wanted,
 *          we will provide the particular "transfer handle" in that struct
 *          and that should/could/would be used in subsequent
 *          curl_easy_getinfo() calls (or similar). The point being that we
 *          must never expose complex structs to applications, as then we'll
 *          undoubtably get backwards compatibility problems in the future.
 *
 * Returns: A pointer to a filled-in struct, or NULL if it failed or ran out
 *          of structs. It also writes the number of messages left in the
 *          queue (after this read) in the integer the second argument points
 *          to.

 * Name:    curl_multi_strerror()
 *
 * Desc:    The curl_multi_strerror function may be used to turn a CURLMcode
 *          value into the equivalent human readable error string.  This is
 *          useful for printing meaningful error messages.

 *          detected to have "action" on them and let libcurl perform.
