Hello everyone!

This is my problem:
I have a C program that sends/receives data to/from an Ada program
through Network sockets (pkg GNAT.Sockets).

I can send a string from the Ada program to the C program.

BUT I can't send any string (or array of chars) from the C program to
the Ada one: the only thing that works is sending only one character
at a time.

I've tried using 'Read and 'Input member functions of several types
(Chars, String, Interfaces.C.char_array, ...) but nothing worked.

The funniest thing is that inside the C program the send function
seems to be working, since it returns the correct number of characters
sent.
Instead, the Ada program blocks itself on 'Read (or 'Input) function
and freezes.

Do anyone know how to read a char stream coming from a C program? (I'm
using Winsock2 legacy library)

Thank you very very much!!!!
