@var{err}: is a negative integer
@var{level}: the alert level will be stored there
Get an alert depending on the error code returned by a gnutls
function. All alerts sent by this function should be considered
fatal. The only exception is when @code{err} is @code{GNUTLS_E_REHANDSHAKE} ,

renegotiation will be performed.
If there is no mapping to a valid alert the alert to indicate
internal error (@code{GNUTLS_A_INTERNAL_ERROR} ) is returned.
