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 cannot transfer anything without  a  specified
       URL).  You  might want to set some callbacks as well that are called from the library when
       data is available etc. For example CURLOPT_WRITEFUNCTION(3). curl_easy_setopt(3)  is  used
       for all this.

       CURLOPT_URL(3)  is  the  only  option  you  really  must set, as otherwise there can be no
       transfer. Another commonly used option is  CURLOPT_VERBOSE(3)  that  helps  you  see  what
       libcurl  is  doing  under  the  hood,  which  is  useful  when  debugging for example. The
       curl_easy_setopt(3) man page has a full index of the over 300 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
       performs  the entire transfer operation and does not 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  are done, cleanup the session by calling curl_easy_cleanup(3). If you want persistent
       connections, you do not cleanup immediately, but  instead  run  ahead  and  perform  other
       transfers using the same easy handle.
