CK_PR_FENCE_STORE_L... FreeBSD Library Functions Manual	CK_PR_FENCE_STORE_L...

NAME
     ck_pr_fence_store_load -- enforce ordering	of store operations to load
     operations

LIBRARY
     Concurrency Kit (libck, -lck)

SYNOPSIS
     #include <ck_pr.h>

     void
     ck_pr_fence_store_load(void);

     void
     ck_pr_fence_strict_store_load(void);

DESCRIPTION
     The ck_pr_fence_store_load() function enforces the	ordering of any	memory
     store, ck_pr_store() and atomic read-modify-write operations to load op-
     erations relative to the invocation of the	function. This function	always
     serve as an implicit compiler barrier.  A fence will currently always be
     emitted for this operation, including for TSO memory model	targets.

EXAMPLE
	   #include <ck_pr.h>

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

	   void
	   function(void)
	   {
		   unsigned int	snapshot_b;

		   ck_pr_store_int(&a, 1);

		   /*
		    * Guarantee	that the store to a is completed
		    * with respect to load from	b.
		    */
		   ck_pr_fence_store_load();
		   snapshot_b =	ck_pr_load_int(&b, 2);
		   return;
	   }

RETURN VALUES
     This function has no return value.
