VRemove

VRemove Remove vertical retrace interrupt task

#include <Retrace.h> Vert. Retrace Mgr

OSErr VRemove(vblTaskPtr );

QElemPtr vblTaskPtr ; address of a 14-byte VBLTask structure

returns 16-bit Error Code; 0=no error

VRemove removes a previously- installed vertical retrace task from the VBL

queue and stops the task from being executed on subsequent retrace interrupts.

vblTaskPtr is the address of a 14-byte VBLTask structure you installed

previously via VInstall.

Returns: an Error Code indicating success or failure of the function. It will

be one of:

noErr (0) no error

qErr (-1) No such task exists

vTypErr (-2) VBLTask.qType must be vType

Notes: It is probably NOT wise to remove tasks you did not install.
