Is there a format specifier that always means a char string with _tprintf?

When you create an application on Windows with support TCHAR, %sin _tprintf()means a line char *for Ansi lines and wchar_t *for Unicode assemblies, but it %smeans the opposite.

But are there any format specifiers that always mean a string char *, whether it is an Ansi or Unicode assembly? Since even in Windows UTF-16 is not actually used for files or networks, it turns out that it is still quite common that you need to deal with byte strings, regardless of the type of native character that you are compiling as an application.

The modifier hforces both %s, and %son char*, and the modifier lforces both wchar_t*, i.e. %hs, %hs, %ls, And %ls.

This may also solve your problem:

_TCHAR *message;
_tprintf(_T("\n>>>>>> %d") TEXT(" message is:%s\n"),4,message);

#ifdef _UNICODE

#define PF_UNICODESTR  "%s"L
#else
#define PF_ASCIISTR    "%s"
#define PF_UNICODESTR  "%S"

PF_ASCIISTR PF_UNICODESTR , C:

_tprintf(_T("There are %d ") PF_ASCIISTR _T(" over the table"), 10, "pens");
