DESCRIPTION
     These functions are OpenPAM extensions to the PAM API.  Those named pam_*() are, in the author's opin-ion, opinion,
     ion, logical and necessary extensions to the standard API, while those named openpam_*() are either
     simple convenience functions, or functions intimately tied to OpenPAM implementation details, and
     therefore not well suited to standardization.
