ck_pr_fence_load_depends(3)                 DragonFly Library Functions Manual

NAME
     ck_pr_fence_load_depends - data dependency barrier

LIBRARY
     Concurrency Kit (libck, -lck)

SYNOPSIS
     #include <ck_pr.h>

     void
     ck_pr_fence_load_depends(void);

DESCRIPTION
     The ck_pr_fence_load_depends(3) emits necessary fences for pure data-
     dependent loads. It currently only serves as a compiler barrier for
     Concurrency Kit's supported platforms. Unless you're on architecture
     which re-orders data-dependent loads (such as the defunct Alpha), this
     function is unnecessary.

RETURN VALUES
     This function has no return value.
