IOP.FLIM
This trap returns the allowable limits of a window.
| Call Parameters | Return Parameters |
|---|---|
| D0 = $6C | D0 = Error return |
| D2 = 0 | D2 preserved |
| D3.W = timeout | D3 preserved |
| A0 = window ID | A0 preserved |
| A1 = pointer to result area | A1 preserved |
Errors
| ICHN | channel not open |
| IPAR | invalid parameter (D2 <> 0) |
Note
A1 points to a four-word area of memory into which the limits are returned in the usual X-size, Y-size, X-origin, Y-origin format. These are absolute co-ordinates.
Example
It is assumed that A0 contains the ID of the window channel.
