/*
* $Id$
*
* This file is a list of handy libc wrappers that attempt to provide some
* thread-safe and other convenient functionality to modules in a form that
* is common, but not dynamically linked with yet another dynamic pam
* library extension.
*
* A number of these functions reserve space in a pam_[sg]et_data item.
* In all cases, the name of the item is prefixed with "_pammodutil_*".
*
* On systems that simply can't support thread safe programming, these
* functions don't support it either - sorry.
