I'm curious what overhead DJGPP's DOS extender imposes on programs in general (I've been able to find no documentation on-line pertaining to the functionality of DOS extenders). In particular, I'd like to know what overhead is imposed by DJGPP's DOS extender for interrupt handling (in GNAT Ada - although I can't see why it should be any different in C). -- * Greg Bond * Dept. of Electrical Eng. * email: bond@ee.ubc.ca * Univ. of British Columbia * voice: (604) 822 0899 * 2356 Main Mall * fax: (604) 822 5949 * Vancouver, BC * web: http://www.ee.ubc.ca/~bond * Canada, V6T 1Z4
