String-based APIs are deprecated [since mbed-os-5.15]

Mbed OS

Just when everything works with no warnings, next day they’re back :slight_smile:

Can anyone help with this:

return ((TLSSocket*)_socket)->connect(host, port);
printf("IP address: %s\n", network->get_ip_address());
printf("Netmask: %s\n", network->get_netmask());
printf("Gateway: %s\n", network->get_gateway());

if ((r = socket->connect(FirebaseID, 443)) != NSAPI_ERROR_OK) {
    printf("TLS socket connect failed (%d)\n", r);
}

The above 5 lines give these string based depreciated warnings.

Warning: ‘get_netmask’ is deprecated: String-based APIs are deprecated [since mbed-os-5.15] [-Wdeprecated-declarations]

Considering I’m the thickest person on the planet, could someone give me an example to correct these please?

Many thanks

Hi Paul,

If network is NetworkInterface then you should give pointer to
SocketAddress a;
net->get_ip_address(&a);
printf(“IP address: %s\n”, a.get_ip_address() ? a.get_ip_address() : “None”);
net->get_netmask(&a);
printf(“Netmask: %s\n”, a.get_ip_address() ? a.get_ip_address() : “None”);
net->get_gateway(&a);
printf(“Gateway: %s\n”, a.get_ip_address() ? a.get_ip_address() : “None”);

I hope this helps. If not hopefully somebody who knows better answers.

Regards,
Pekka

Thanks Pekka,
Yes your example worked, but had a couple other ‘stringy API’ problems and Jan kamidra had the answers:

How to get IP, NETMASK. GATEWAY:

    SocketAddress ip = "192.168.1.1";
    SocketAddress mask = "255.255.255.0";
    SocketAddress gateway = "10.0.1.138";
    eth.set_network(ip,mask,gateway); 
//or retype string
    eth.set_network((SocketAddress)"192.168.1.1",(SocketAddress)"255.255.255.0",(SocketAddress)"10.0.1.138");
//or retype macro
    eth_stat = eth.set_network((SocketAddress)IP,(SocketAddress)MASK,(SocketAddress)GATEWAY);

add to get:
the first one is ok from my point of view. The .get_ip_address was change to same design like .set_ip_address . It return nsapi_error and the address is returned via object of SocketAddress which need to be placed as input parameter and then read the content of that object.

    SocketAddress check; 
    eth.get_ip_address(&check);
    printf("IP address: %s\n", check.get_ip_address() ? check.get_ip_address() : "None");
    eth.get_netmask(&check);
    printf("Netmask: %s\n", check.get_ip_address() ? check.get_ip_address() : "None");
    eth.get_gateway(&check);
    printf("Gateway: %s\n", check.get_ip_address() ? check.get_ip_address() : "None");

Now no string based errors :slight_smile:
