CSimpleStringT::operator PCXSTR 

Directly accesses characters stored in a CSimpleStringT object as a C-style string.


operator PCXSTR( ) const throw( );

A character pointer to the string's data.

No characters are copied; only a pointer is returned. Be careful with this operator. If you change a CString object after you have obtained the character pointer, you may cause a reallocation of memory that invalidates the pointer.

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[1024];

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;
