Directly accesses characters stored in a CSimpleStringT object as a C-style string.
The following example demonstrates the use of CSimpleStringT::operator PCXSTR.
// If the prototype of a function is known to the compiler, // the PCXSTR cast operator may be invoked implicitly. CSimpleString strSports(L"Soccer is Best!", pMgr); WCHAR sz; wcscpy_s(sz, strSports); // If the prototype isn't known or is a va_arg prototype, // you must invoke the cast operator explicitly. For example, // the va_arg part of a call to swprintf_s() needs the cast: swprintf_s(sz, 1024, L"I think that %s!\n", (PCWSTR)strSports); // While the format parameter is known to be an PCXSTR and // therefore doesn't need the cast: swprintf_s(sz, 1024, strSports); // Note that some situations are ambiguous. This line will // put the address of the strSports object to stdout: wcout << strSports; // while this line will put the content of the string out: wcout << (PCWSTR)strSports;
