This instruction stops the program (thus the task) until the condition expressed becomes true.

Syntax

mt_wait (cond)

cond

It is any expression

Validity

Task

Note

It should normally be used in tasks whose execution is required on command (event). In fact, tasks, by standing idle, leave more execution time for other tasks (time-sharing).

To stop the task for an interval of time use dwell

Examples of use:

; The task remains stationary until one of two conditions occurs.

mt_wait(inp(3) or out(17))

; The task remains stopped until the volatile integer register r(17) takes value 1000

mt_wait(r(17) = 1000)

 

; Passing constant 0 stops the task forever

mt_wait(0)

 

;If you pass a constant other than 0, even decimal, the function never blocks

mt_wait(0.2)
