This call is mostly for the i386 architecture. On many other
architec-
tures it does not exist or will always return an error.
Switching to C will not cause this function to magically appear in the
Linux kernel on non-i386 systems.
Hi Jonas,
this seems to work on a 64-bit-system:
#include <sys/io.h>
int
main(int argc, char *argv[])
{
unsigned char b;
if (iopl(3) == -1)
perror("iopl");
b = inb(0xec00);
printf("b=%#x\n", b);
}
It is c, but now I simply need to know how to call c functions in pascal
programs. I am using a linux kernel in version 2.6.28, and for this
kernel version your quotation of "man iopl" seems not to be valid.
Holger
