   7  * This file is a list of handy libc wrappers that attempt to provide some
   8  * thread-safe and other convenient functionality to modules in a form that
   9  * is common, but not dynamically linked with yet another dynamic pam
  10  * library extension.
  11  *
  12  * A number of these functions reserve space in a pam_[sg]et_data item.
  13  * In all cases, the name of the item is prefixed with "_pammodutil_*".
  14  *
  15  * On systems that simply can't support thread safe programming, these
  16  * functions don't support it either - sorry.
