1 Subject: timer_add()/timer_remove() macros
3 This adds two new macro subroutines for handling timeouts.
5 **timer_add( func_name, timeout [, "global"] )**
6 Install a new timer that call the macro routine ~func_name~ after ~timeout~
7 milli seconds. The function is only called if the top window is the same as
8 the window from which ~timer_add()~ was called, this can be overriden with the
9 optional ~"global"~ parameter. The macro returns a timer ID which can be used
10 to remove a timer before expiration with ~timer_remove()~.
12 **timer_remove( timer_ID )**
13 Removes the timer with ID ~timer_ID~.
15 There can be a problem on LP64 architectures, the nedit macro language have
16 only int support but the XtIntervalId is defined as unsigned long, so there
17 can be domain error, I try to catch this error.
