info needed on atomic operations

Hi all,

I need some information on atomic operations. Please provide me some information on how do I do the following operations atomically(for iX86):
(1) set a charecter ( dst = src),
(2) compare and then set a charecter ( if (dst==X) dst = src;)

It would be great If you provide some references to any good documents.

Thanks,
Srini

Srinivas,

What exactly are trying to do? Are you working in user- or in kernelspace? What kernel? What programming language?

Cheers

Jake
