/*
 * \brief Checks that the address, port and flags given are valids and it returns an 'addrinfo' structure.
 *
 * This function basically calls the getaddrinfo() calls, and it performs a set of sanity checks
 * to control that everything is fine (e.g. a TCP socket cannot have a mcast address, and such).
 * If an error occurs, it writes the error message into 'errbuf'.
 *
 * \param host: a pointer to a string identifying the host. It can be
 * a host name, a numeric literal address, or NULL or "" (useful
 * in case of a server socket which has to bind to all addresses).
 *
 * \param port: a pointer to a user-allocated buffer containing the network port to use.
 *
 * \param hints: an addrinfo variable (passed by reference) containing the flags needed to create the
 * addrinfo structure appropriately.
 *
 * \param addrinfo: it represents the true returning value. This is a pointer to an addrinfo variable
 * (passed by reference), which will be allocated by this function and returned back to the caller.
 * This variable will be used in the next sockets calls.
 *
 * \param errbuf: a pointer to an user-allocated buffer that will contain the complete
 * error message. This buffer has to be at least 'errbuflen' in length.
 * It can be NULL; in this case the error cannot be printed.
 *
 * \param errbuflen: length of the buffer that will contains the error. The error message cannot be
 * larger than 'errbuflen - 1' because the last char is reserved for the string terminator.
 *
 * \return '0' if everything is fine, '-1' if some errors occurred. The error message is returned
 * in the 'errbuf' variable. The addrinfo variable that has to be used in the following sockets calls is
 * returned into the addrinfo parameter.
 *
 * \warning The 'addrinfo' variable has to be deleted by the programmer by calling freeaddrinfo() when
 * it is no longer needed.
 *
 * \warning This function requires the 'hints' variable as parameter. The semantic of this variable is the same
 * of the one of the corresponding variable used into the standard getaddrinfo() socket function. We suggest
 * the programmer to look at that function in order to set the 'hints' variable appropriately.
