Class JavaLibCHelper

java.lang.Object

jnr.posix.JavaLibCHelper

public class JavaLibCHelper
extends java.lang.Object

This libc implementation is created one per runtime instance versus the others which are expected to be one static instance for whole JVM. Because of this it is no big deal to make reference to a POSIXHandler directly.
