63 | Print a fatal error message and kill the process. No cleanup is | |
64 | performed. This function should only be invoked when a condition is | |
65 | detected that would make it dangerous to continue using the Python | |
66 | interpreter; e.g., when the object administration appears to be | |
67 | corrupted. On <span class="Unix">Unix</span>, the standard C library function | |
68 | <tt class="cfunction">abort()</tt><a id='l2h-165' xml:id='l2h-165'></a> is called which will attempt to | |
69 | produce a <span class="file">core</span> file. | |

75 | Exit the current process. This calls | |
76 | <tt class="cfunction">Py_Finalize()</tt><a id='l2h-166' xml:id='l2h-166'></a> and then calls the | |

84 | Register a cleanup function to be called by | |
85 | <tt class="cfunction">Py_Finalize()</tt><a id='l2h-168' xml:id='l2h-168'></a>. The cleanup | |
86 | function will be called with no arguments and should return no | |
87 | value. At most 32 <a id='l2h-169' xml:id='l2h-169'></a>cleanup functions can be | |
88 | registered. When the registration is successful, | |
89 | <tt class="cfunction">Py_AtExit()</tt> returns <code>0</code>; on failure, it returns | |
90 | <code>-1</code>. The cleanup function registered last is called first. | |
91 | Each cleanup function will be called at most once. Since Python's | |
92 | internal finalization will have completed before the cleanup | |
93 | function, no Python APIs should be called by <var>func</var>. | |
