Can You suggest me how create the function receive_phrase terminated
with "..".

Tough. I can't imagine a function that requires passing the same argument
twice. ;)

Anyhow, let's sum up what you need:
1. A way to signal errors like e.g. a broken connection or allocation
failure.
2. A way to pass out arbitrary amounts of dynamically allocated data and
their length.

If you have that, the rest is just implementing it.

BTW: read the FAQ about homework.
