Name: call_out_info - get information about all call_outs running

Syntax:
	mixed **call_out_info()

Description:
	The call_out_info efun gets information about all running call_outs
	at the moment.

	It is used by the 'call_outs' wizard command so please avoid re-
	implementing it.

Return value:
	It returns an array of all pending call_outs. The array contains

		object arr[i][0]: object in which the call_out() is running,
		string arr[i][1]: name of to be called function
		int    arr[i][2]: time in seconds until function will be called
		mixed  arr[i][3]: the argument to be passed to the function

	where i is the array-member.
	There might also be elements in the returned array that are zero,
	these are call_outs for destructed objects. Don't forget to check
	that if you run through the array!

Examples: none

Note:
	For checking one specific call_out in the current object see efun
	find_call_out.
