NAME

       ck_pr_fence_store_atomic — enforce ordering of store operations to load operations

LIBRARY

       Concurrency Kit (libck, -lck)

SYNOPSIS

       #include <ck_pr.h>

       void
       ck_pr_fence_store_atomic(void);

       void
       ck_pr_fence_strict_store_atomic(void);

DESCRIPTION

       The  ck_pr_fence_store_atomic()  function  enforces  the  ordering of any memory store, ck_pr_store() and
       atomic read-modify-write operations to atomic read-modify-write operations relative to the invocation  of
       the  function.  This  function  always serve as an implicit compiler barrier.  This functions will emit a
       fence  for  PSO  and  RMO  targets.  In  order   to   force   the   emission   of   a   fence   use   the
       ck_pr_fence_strict_store_atomic() function.

EXAMPLE

             #include <ck_pr.h>

             static int a = 0;
             static int b = 0;

             void
             function(void)
             {

                     ck_pr_store_int(&a, 1);

                     /*
                      * Guarantee that the store to a is completed
                      * with respect to the update of b.
                      */
                     ck_pr_fence_store_atomic();
                     ck_pr_add_int(&b, 2);
                     return;
             }

RETURN VALUES

       This function has no return value.
