You can control the DOS error requesters by setting the pr_WindowPtr
variable in the process structure.  Setting it to zero causes error
requesters to appear on the workbench screen (default behavior.)
Setting it to -1 causes the requesters to not appear, with the
error returned to the program.  Or you can put a pointer to a window
in it, and the requester should appear in that window (or at least
on the same screen as the window.)  This is documented in "The
AmigaDOS Manual" by Bantam Books, ISBN 0-553-34294-0.  It is near
the end, in the section on AmigaDOS Data Structures.
