Re: Where are inb/outb macros?

inb/outb could be used from the usr space on x86 class PC-computer to access
to io ports this is what i assume that you are trying 

You need to compile the program with -O option (expantion of Inline function
)

To perform io operation on ports ioprem/iopl system call must be used (To
get permissio to perform io operation)

Program must run as root 

on non 86 platform try using /dev/port device file in the application

Hello All!
I can't compile one small software title because of lack <sys/io.h>
and inb/outb macros. What sould I do to overcome this obstacle?

My linux distro is Fedora 7 if it is matter.

They don't exist in user space on non-x86. You have to do things
differently. What is your software trying to do ? If it's trying to
access a PCI device IO space, you probably want to mmap it in sysfs and
write your own accessors with appropriate memory barriers.

All cases where I've seen application software use <sys/io.h>, there was
actually a full device driver in the kernel that already exported a 
high-level interface to user space. If that's the case here, the
application
should use that instead of sysfs.
