When programming in C (not C++) how does one send information to a
hardware device such as a video card or modem? How is this done in
Linux C programming versus Microsoft C programming?
Take a look at following C code which directly communicate with
Monitor and Fills the entire screen with letter 'A'. You don't need
the printf statement.
#include<stdio.h>
#include<conio.h>
void main()
{
int i;
char far *vidmem=0xB8000000;
for(i=0;i<=3999; i=i+2)
*(vidmem+i)='A';
}
for more C programs and assembly language codes which directly
communicates with hardware go to
