Question

I am attempting to construct a very simple proof of concept that I can write a web service and actually call the service from a symbian environment. The service is a simple Hello service which takes a name in the form of a const char* and returns back a greeting of the form “hello ” + name in the form of a char*. My question is, how do I convert a char* to a TPtrC16 so that I can use the console->Write function to print out the response to screen? I know I could search through the API and figure this out, but for a basic conceptual demo I’d rather not spend the time (not sure that Symbian is something I will ever work with again).

Thanks!

If the const char* string is in US-ASCII, you can use TDes::Copy to copy it wrapped in a TPtrC8 to a 16-bit descriptor:

const char *who = "world";
TBuf<128> buf;
buf.Copy(TPtrC8((TText8*)who));
console->Printf(_L("hello %S\n"), &buf);

If it is in some other encoding, have a look at the charconv API in the SDK help.
