NAME

       curl_easy_init - create an easy handle

SYNOPSIS

       #include <curl/curl.h>

       CURL *curl_easy_init();

DESCRIPTION

       This  function allocates and returns an easy handle. Such a handle is used as input to other functions in
       the easy interface. This call must have a corresponding call to curl_easy_cleanup(3) when  the  operation
       is complete.

       The  easy  handle  is  used to hold and control a single network transfer. It is encouraged to reuse easy
       handles for repeated transfers.

       An  alternative  way  to  get  a  new  easy  handle  is  to  duplicate  an  already  existing  one   with
       curl_easy_duphandle(3),  which  has  the  upside that it gets all the options that were set in the source
       handle set in the new copy as well.

       If you did not already call curl_global_init(3) before calling this function, curl_easy_init(3)  does  it
       automatically.  This can be lethal in multi-threaded cases for platforms where curl_global_init(3) is not
       thread-safe, and it may then result in resource problems because there is no corresponding cleanup.

       You are strongly advised to not allow this automatic behavior, by  calling  curl_global_init(3)  yourself
       properly.  See the description in libcurl(3) of global environment requirements for details of how to use
       this function.

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 7.1

RETURN VALUE

       If this function returns NULL, something went wrong and you cannot use the other curl functions.
