/* onfork.c: This module allows code to register `onfork' handlers, similar
|
|
* to the way exit handlers are registered in C with atexit().
|
|
* The interpreter kernel proper never calls the onfork handlers,
|
|
* but the fork primitive of the UNIX extension does in the newly
|
|
* created child process (other extensions may also call the handlers).
|
|
*
|
|
* The dynamic loading implementation of the interpreter kernel
|
|
* may register onfork handlers to add links to the temp files.
|
|
* User-supplied extensions may want to register onfork handlers
|
|
* as well.
