NAME

killreq - disables Intuition's AutoRequest() function

SYNOPSIS

killreq [disable | enable]

DESCRIPTION

Killreq is a freely distributable utility which stops Intuition from displaying AutoRequesters. Instead, any program which tries to display an AutoRequester will be fooled into thinking the user selected the CANCEL option. In particular, AmigaDOS requesters will not be displayed. These include "Please insert volume xyzzy:", "Disk Full" and "Volume xyzzy: has a Read/Write error".

Similar programs (such as NoReq) already exist, but these only affect requesters connected with a particular CLI window. KillReq will disable requesters on a systemwide basis. This is particularly useful if you use your Amiga remotely a lot, since some programs (BBS-PC springs to mind) can generate AutoRequesters even when they have been disabled.

Invoking killreq with no parameters displays a brief usage method. Otherwise, you should specify either `disable' or `enable' (only the first letter is actually checked). `disable' will stop Intuition from displaying AutoRequesters and `enable' will allow AutoRequesters to be displayed again.

OPERATION

Killreq tries to be as friendly to the operating system as possible. It SetFunction()'s the AutoRequest() function in Intuition's library to point to a stub routine which simply returns FALSE. If another program tries to SetFunction() AutoRequest(), killreq will still allow itself to be disabled without pulling the rug out from under the second program. It tries to guarantee that the system is in a "safe" state at all times.

In fact, a program that does basically the same thing as killreq could be written in around 50 bytes of machine-code (or less), but since this is such a simple application of SetFunction(), it seemed worth the extra code to do it "properly" as an example for more sophisticated usages.
