Tcl API Reference -- ns_schedule_proc

### ns_schedule_proc

#### Overview

Schedule a procedure to run at specified intervals

#### Syntax

ns_schedule_proc ?-thread? ?-once? interval {script | procname ?args?}

#### Description

ns_schedule_proc runs the specified Tcl script or procedure (procname) at an interval specified by interval. The interval is the number of seconds between runs of the script.

Specify -thread if you want a thread created to run the procedure. This will allow the scheduler to continue with other scheduled procedures. Specifying -thread is appropriate in situations where the script will not return immediately, such as when the script performs network activity.

Specify -once if you want the script to run only one time. The default is that the script will be re-scheduled after each time it is run.

ns_schedule_proc returns an id number for the scheduled procedure that is needed to stop the scheduled procedure with ns_unschedule_proc.

#### Example

        proc dosomething blah {
            ns_log Notice "proc with arg '$blah'"
        }
        ns_schedule_proc 10 dosomething $arg1
