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. CSimpleStringT strSports( _T ( "Soccer is Best!" ) ); TCHAR sz; lstrcpy( 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 sprintf( ) needs the cast: sprintf( sz, "I think that %s!\n", ( PCXSTR ) strSports ); // While the format parameter is known to be an PCXSTR and // therefore doesn't need the cast: sprintf( sz, strSports ); // Note that some situations are ambiguous. This line will // put the address of the strSports object to stdout: cout << strSports; // while this line will put the content of the string out: cout << ( PCXSTR ) strSports;
