# ck\_pr\_fence\_load\_depends(3)

data dependency barrier

## 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.
