* This file is a list of handy libc wrappers that attempt to provide some
* thread-safe and other convenient functionality to modules in a common form.
*
* 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 "pam_modutil_*".
*
* On systems that simply can't support thread safe programming, these
* functions don't support it either - sorry.
