In C I know how to read() in a loop and increment a pointer to a buffer
(a C string) while receiving characters until there are no more of
them. It is sufficient that read() returns how many characters has
already read and some little math involving buffer size.

In Ada I don't know how to do it... Can you please give me any
suggestions?

Thank you in advance.
