how to read/write to ports hello i am trying to read/write a value to a port (240h for example) but whenever i use inportb() or outportb() my compiler (bloodshed DEV++) flags it as a reference as an undefined function. i have included the stdio.h, conio.h and dos.h files but still nothing. my sample code is:
#include <stdio.h>
#include <conio.h>
#include <dos.h>
int main()
{
int inportb();
int result;
while(1)
{
result= inportb(0x240);
printf("Result is %d",result);
}
rteurn 0;
}
Don't know for sure.
But sometimes, believe it or not, just re-ordering the #include files does the trick! I've had a similar problem solved this way.
It's a long shot, but...
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
BTW, in my system, Win '98, Bloodshed Dev compiler, "inportb" for instance, is referenced in WAVE.h ...
