Documentation for linux64 syscalls?

[nobody]

I've been scouring the net trying to find the syscall documentation for the 64-bit linux kernels.  No luck so far.
I've found a list of them in /usr/include/asm/unistd_64.h, but the comments aren't very helpfull.

Anybody have a link for me?

Also, one more thing I've been unable to figure out, what's the difference between syscall (using nasm, of course) and int 80h?  Syscall works, but 80h segfaults.  I really need to find out what syscall is doing.

Thanks in advance,

Ok.  Figured out the syscall thing.  Not supposed to do int 80h directly in linux64.

Now all I'm looking for is the docs on the syscall function codes.

I found what I was looking for.  Here goes:

The fuction names & numbers from /usr/include/asm/unistd_64.h.

The function descriptions are in manpages!  Do a 'man llseek', for instance.
The latest manpages can be downloaded from http://www.kernel.org/pub/linux/docs/manpages/ if for some reason someone doesn't have man2.
And of course the ABI is important.  I got mine from http://www.x86-64.org/documentation.html.

Oops.  the second link doesn't work because of the trailing dot.
