you may need to add extra checks (for instance, checking whether the char pointer is null or not).

Converting descriptors to C-strings may be done this way:

const char* descriptorToStringL(const TDesC& aDescriptor)

{

TInt length = aDescriptor.Length();

HBufC8* buffer = HBufC8::NewLC(length);

buffer->Des().Copy(aDescriptor);

char* str = new(ELeave) char[length + 1];

Mem::Copy(str, buffer->Ptr(), length);

str[length] = '';

CleanupStack::PopAndDestroy(buffer);

return str;

}
