# The SyncReaderWriter class

(PECL sync >= 1.0.0)

## Introduction

A cross-platform, native implementation of named and unnamed reader-writer objects.

A reader-writer object allows many readers or one writer to access a resource. This is an efficient solution for managing resources where access will primarily be read-only but exclusive write access is occasionally necessary.

## Class synopsis

public bool readlock ([ integer `$wait` ] )
