| 61 | The modules described in this chapter provide interfaces to operating | |
| 62 | system features that are available on (almost) all operating systems, | |
| 63 | such as files and a clock. The interfaces are generally modeled | |
| 64 | after the <span class="Unix">Unix</span> or C interfaces, but they are available on most | |
| 65 | other systems as well. Here's an overview: | |
