I would like to write a C program using DJGPP to record data from an ISA ADC
card. The card generates around 10,000 interrupts per second. I am using a
486dx2 (66Mhz) PCI based PC. Polling the card is not an option. I already
have a real-mode C program for reading the card data and it seems to work fine
at up to 10,000 ints per sec, but it really needs to be 32-bit (I need more
than 256x256 arrays).

Is this likely to be a problem with djgpp? 

any help would be greatly appreciated

David
