[ug-bosug] How to use CAS Instruction (or) atomic Function in C programs.

[Pramod Batni]

The atomic operations are available as Standard C Library  functions
[atomic_add_16, atmoic_add_32..] which are declared in atomic.h .
For more details on the atomic operations please refer to 'man -s 3C atomic_ops'

header. When i used this header file in the C program and try to
compile it is showing no such header file is there. Actually we want
to know which libraries to include to use CAS instruction. Can any one
who know how to use CAS instruction in solaris 10 (using gcc compiler)
,please inform us.
