Subject: RE: setscreen() function usage

Author: earx (gw-ehv05.pnl.philips.com) Date: 01-10-2003 14:23 well, you could declare arrays. a bit like you said. but you don't need 32000 longs (=128000 bytes). you need 32000 _bytes_. 320*200*4bit=64000*4bit=256000bits=32000bytes.. /* note the 256 byte boundary we have to keep in mind */ unsigned char buf1[32000+256]; unsigned char buf2[32000+256]; /* the pointers */ unsigned char *phys; unsigned char *log; void main() { unsigned char* temp; /* temp pointer for swap */ /* * initialize pointers... * note that they are put on 256byte bounds */ phys=(buf1+255)&0xFFFFFF00; log=(buf2+255)&0xFFFFFF00; /* your loop */ while(!kbhit()) { /* paint some stuff */ /* swap pointers */ temp=phys; phys=log; log=temp; /* wait for vbl with some xbios call.. */ /* setscreen */ } /* read some key here, otherwise os nags ;) */ /* ehmm.. end ;) */ } this was just some stuff i wrote in 2 secs, i didn't check to see if it was 100% correct. good luck!
