| 57 | </H2> | |

| 59 | <P> | |
| 60 | Module <tt class="module">posix</tt> defines the following data item: | |
| 61 | ||
| 62 | <P> | |
| 63 | <dl><dt><b><tt id='l2h-2971' xml:id='l2h-2971'>environ</tt></b></dt> | |
| 64 | <dd> | |
| 65 | A dictionary representing the string environment at the time the | |
| 66 | interpreter was started. For example, <code>environ['HOME']</code> is the | |
| 67 | pathname of your home directory, equivalent to | |
| 68 | <code>getenv("HOME")</code> in C. | |
| 69 | ||
| 70 | <P> | |
| 71 | Modifying this dictionary does not affect the string environment | |
| 72 | passed on by <tt class="function">execv()</tt>, <tt class="function">popen()</tt> or | |
| 73 | <tt class="function">system()</tt>; if you need to change the environment, pass | |
| 74 | <code>environ</code> to <tt class="function">execve()</tt> or add variable assignments and | |
| 75 | export statements to the command string for <tt class="function">system()</tt> or | |
| 76 | <tt class="function">popen()</tt>. | |
| 77 | ||
| 78 | <P> | |
| 79 | <span class="note"><b class="label">Note:</b> | |
| 80 | The <tt class="module"><a href="module-os.html">os</a></tt> module provides an alternate | |
| 81 | implementation of <code>environ</code> which updates the environment on | |
| 82 | modification. Note also that updating <code>os.environ</code> will render | |
| 83 | this dictionary obsolete. Use of the <tt class="module"><a href="module-os.html">os</a></tt> module version of | |
| 84 | this is recommended over direct access to the <tt class="module">posix</tt> module.</span> | |

| 87 | <P> | |
| 88 | Additional contents of this module should only be accessed via the | |
| 89 | <tt class="module"><a href="module-os.html">os</a></tt> module; refer to the documentation for that module for | |
| 90 | further information. | |
