DESCRIPTION

These functions are OpenPAM extensions to the PAM API. Those named pam_*() are, in the author's opinion, 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.
