## SYNOPSIS

handle:flush()

## DESCRIPTION

Discards any data present in the receive buffer, but not yet read by the application.

## RETURN VALUE

On success, returns true. On failure, returns nil. In case of an error, the error can be retrieved using rawio:lastError().

## ERRORS

This function works only on TTY devices.

## NOTES

You can never be sure that the receive buffer is empty afterwards, since data may arrive right after the call to rawio:drain().
