libcurl-easy(3)



NAME

   libcurl-easy - easy interface overview

DESCRIPTION

   When  using  libcurl's "easy" interface you init your session and get a
   handle (often referred to as an "easy handle"), which you use as  input
   to  the  easy interface functions you use. Use curl_easy_init(3) to get
   the handle.

   You continue by setting all  the  options  you  want  in  the  upcoming
   transfer,  the  most  important among them is the URL itself (you can't
   transfer anything without a specified URL as you may have  figured  out
   yourself).  You  might  want to set some callbacks as well that will be
   called from the library when data is available etc. curl_easy_setopt(3)
   is used for all this.

   CURLOPT_URL(3)  is  only option you really must set, as otherwise there
   can be no transfer. Another commonly used option is  CURLOPT_VERBOSE(3)
   that  will  help  you  see  what  libcurl is doing under the hood, very
   useful when debugging for example. The curl_easy_setopt(3) man page has
   a full index of the over 200 available options.

   If  you at any point would like to blank all previously set options for
   a single easy handle, you can call curl_easy_reset(3) and you can  also
   make  a  clone  of  an  easy  handle  (with  all its set options) using
   curl_easy_duphandle(3).

   When all is setup, you tell  libcurl  to  perform  the  transfer  using
   curl_easy_perform(3).   It  will then do the entire operation and won't
   return until it is done (successfully or not).

   After the transfer has been made, you can  set  new  options  and  make
   another  transfer,  or  if  you're done, cleanup the session by calling
   curl_easy_cleanup(3). If you want  persistent  connections,  you  don't
   cleanup  immediately, but instead run ahead and perform other transfers
   using the same easy handle.
