1 NAME
2 call_out - call function with delay

4 SYNOPSIS
5 int call_out(string function, mixed delay, mixed args...)

8 DESCRIPTION
9 Call a function in the current object with a delay. The function to
10 be called must not be private. The delay is specified in seconds.
11 The minimum delay is 0 seconds, for a function that is to be called
12 as soon as possible after termination of the current thread.
13 If the delay is an integer, the function will be called after
14 approximately the specified number of seconds. Otherwise, the delay
15 must be a floating point number less than or equal to 60.0, and the
16 function will be called with a millisecond resolution.
17 The returned value is the callout handle, an integer > 0 which must be
18 used if the callout is to be removed.

20 ERRORS
21 If the number of active delayed calls in the system is equal to the
22 value of the ST_COTABSIZE field of the array returned by status(),
23 where ST_COTABSIZE is defined in the include file <status.h>,
24 attempting to add another one will result in an error.
25 If the maximum number of callouts is set to 0, no delayed call will
26 be added, and no error will be caused.
