 * @param mask   An integer representing the types of messages desired.
 *               Acceptable values are created through bitwise ORs of 
 *               REGFI_LOG_* values.  For instance, if only errors and
 *               informational messages were desired (but not warnings),
 *               then one would specify: REGFI_LOG_ERROR|REGFI_LOG_INFO
 *               By default the message mask is: REGFI_LOG_ERROR|REGFI_LOG_WARN.
 *
 * @return       true on success and false on failure.  Failure occurs if 
 *               underlying pthread functions fail.  errno is set in this case.
 *
 * Message masks are set in a thread-specific way.  If one were to set a message
 * mask in one thread and then spawn a new thread, then the new thread will have
 * it's message mask reset to the default.  This function may be called at any 
 * time and will take effect immediately for the current thread.
 *
 * @note When a non-zero message mask is set, messages will
 *       accumulate in memory without limit if they are not fetched using
 *       @ref regfi_get_log_str and subsequently freed by the caller.  It is
 *       recommended that messsages be fetched after each regfi API call in
 *       order to provide the most context.
