The subsequent sections will show how to write Eiffel classes with their features. In an Eiffel system, however, not everything has to be written in Eiffel: some features may be '''external''' , coming from languages such as C, C++, Java, C# Fortran and others. For example a feature declaration may appear (in lieu of the forms seen later) as
<code>
file_status (filedesc: INTEGER): INTEGER
-- Status indicator for filedesc
external
"C" alias "_fstat"
end
file_status (filedesc: INTEGER): INTEGER
-- Status indicator for filedesc
external
"C" alias "_fstat"
end
</code>
to indicate that it is actually an encapsulation of a C function whose original name is <code>fstat _</code>. The <code>alias</code> clause is optional, but here it is needed because the C name, starting with an underscore, is not valid as an Eiffel identifier.
