curl_easy_init - Start a libcurl easy session
CURL *curl_easy_init( );
This function must be the first function to call, and it returns a CURL easy
handle that you must use as input to other functions in the easy
interface. This call MUST
have a corresponding call to
when the operation is complete.
If you did not already call curl_global_init(3), curl_easy_init(3)
does it automatically. This may be lethal in multi-threaded cases, since
curl_global_init(3) is not thread-safe, and it may 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
If this function returns NULL, something went wrong and you cannot use the
other curl functions.
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
res = curl_easy_perform(curl);
