NAME
- CWait
-
Include copper wait instruction in the user copper list.
SYNOPSIS
CWait( c , v , h )
LONG CWait( struct UCopList *, WORD, WORD)
a1 d0 d1
FUNCTION
Include a instruction to wait for vertical beam position v and horizontal position h to this intermediate copper list. You should also call CBump(c) afterwards to increment the user copper list instruction pointer, or use the CWAIT() macro in first place.
INPUTS
- c
-
pointer to UCopList structure
- v
-
vertical beam position (relative to top of viewport)
- h
-
horizontal beam position
RESULT
A boolean success indicator. Returns non-zero if there was still room in the user copper list to include the move, FALSE if the user copper list is full.
BUGS
Versions prior to V47 did not provide a return code, though may have failed. User waiting for horizontal values of greater than 222 decimal is illegal.
