  • LPWSTR wprintf 规格严格

    因为LPWSTR指向的是一个宽字符串,而printf()是针对通常的字符串(非宽字符串)的,所以两者的类型不匹配,应该使用wprintf()

    s String When used with printf functions, specifies a single-byte–character string; when used with wprintf functions, specifies a wide-character string. Characters are printed up to the first null character or until the precision value is reached.

    #define __T(x) L ## x
    ...
    #define _T(x) __T(x)
    #define _TEXT(x) __T(x)
    ...

    C++ String Literals
    A string literal consists of zero or more characters from the source character set surrounded by double quotation marks ("). A string literal represents a sequence of characters that, taken together, form a null-terminated string.

    Syntax

    string-literal :

    "s-char-sequenceopt"
    L"s-char-sequenceopt"

    ...
    To specify a string of type wide-character (wchar_t[]), precede the opening double quotation mark with the character L. For example:

    wchar_t wszStr[] = L"1a1g";
