How does one disable System Requesters from C. I am writing a small
program that displays free space in both memory and drive (both hard and
floppy) in a small window on the screen. When no disk is in a floppy, the
system asks me to put a disk in it. I just want to display 0 bytes free when
no disk in in the drive.
Thanx in Advance....

In your process structure, there's a pr_WindowPtr field. This is the window the DOS requesters get hung off of. If set to NULL, dos requesters silently fail. (see libraries/dosextens.h) -- -Colin
