CK_PR_FENCE_STORE_A... FreeBSD Library Functions Manual	CK_PR_FENCE_STORE_A...

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 mem-
     ory 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.
