/*
 * OpenSSL provides a framework for pushing error codes onto a stack.
 * When an error occurs, the consumer may use the framework to
 * pop the errors off the stack and provide a trace of where the
 * errors occurred.
 *
 * Our PKCS12 code plugs into this framework by calling
 * ERR_load_SUNW_strings(). To push an error (which by the way, consists
 * of a function code and an error code) onto the stack our PKCS12 code
 * calls SUNWerr().
 *
 * Consumers of our PKCS12 code can then call the OpenSSL error routines
 * when an error occurs and retrieve the stack of errors.
