INETGetURLex2

Send a http request to a specific url with a specific verb (which would probably be POST). This is asynchronous. When server responds, the callback is fired, with following arguments.

a connection object (INET)
an user parameter at your convenience (u0)
the data parameter : depends on the following parameter
the state code :
- 0 : some data has been received, and can be read in the received data parameter
- 1 : end of request. received data is nil. This is the last call of the callback.
- other : an error occured during the request. received data is nil. This is the last call of the callback

Prototype :

fun [Chn S S S S I fun [INET u0 S I] u1 u0] INET

Chn : a channel
S : verb, like "POST", "GET", "PUT" ...
S : url
S : header, if requested
S : content to send
I : the mode should be 0
fun [INET u0 S I] u1 : reflex
u0 : user parameter, at your convenience

Return : INET a connection object or nil if error

Error :

EOK if no error.
ECHN if the channel is nil.
ESTRING if the url is nil.
EFLAG if the mode is not null.
EARG if the verb is too long or seems incorrect.
ETYPE if the initialization fails.
ETHREAD if the new thread fails to create.
EVM if a memory error occurs. The VM will exit and more informations could be found in the log file (if activated in the debug mode level).

INETGetURLex (DEPRECATED) returns the same errors.

Example :

fun send_callback (inet, user_param, data, err)=
	if err == 0 then	// the response is not finished
		// to do something
	else if err == 1 then	// the response is ok and finished
		// to do something
	else		// an error occurs
		// to do something
	0;;

fun send_request (address, verb, param)=
	INETGetURLex2 
		_channel 
		verb	// "POST", "GET", "HEAD", ...
		address
		"content-type: application/x-www-form-urlencoded"	// request header, if any
		param	// content to send
		0	// should stay at 0
		@send_callback	// callback to the response
		0;	// user parameter
	0;;

The function INETGetURLex shound not be used in a new application ! Use this function instead !
