       libcurl-easy - easy interface overview


       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

       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.
