|
This function can be used to retrieve the current value of a certain |
11 |
|
|
parameter of the requested note. If the passed note ID is valid, then |
12 |
|
|
this function returns the note's current value of the requested |
13 |
|
|
parameter type. If the note ID is invalid or the note is no longer |
14 |
|
|
alive, then the value returned by this function is undefined. So you |
15 |
|
|
should call <code>event_status()</code> to ensure the note is still |
16 |
|
|
alive before calling this function. |
17 |
|
|
</p> |
18 |
|
|
<p> |
19 |
|
|
You might use function <code>set_event_par()</code> to change those |
20 |
|
|
parameters. |
