How do I convert Tchar to Wchar?

How do I convert Tchar to Wchar?

TCHAR is wchar_t if compiled with UNICODE turned on. Otherwise, TCHAR is char, and to convert to wchar_t you can use the function “mbstowcs” or “MultiByteToWideChar”.

What does Tchar mean?

When Character Set if set to “Use Multi-Byte Character Set”, TCHAR would mean char . Likewise, to support multiple character-set using single code base, and possibly supporting multi-language, use specific functions (macros).

Is Wchar the same as wchar_t?

wchar_t is a distinct type, defined by the C++ standard. WCHAR is nonstandard, and as far as I know, exists only on Windows. However, it is simply a typedef (or possibly a macro) for wchar_t , so it makes no practical difference.

How big is a Tchar?

if you use _UNICODE the sizeof(TCHAR) == sizeof(unsigned short) meaning 2 bytes!

How do I convert Wstring to Wchar?

typedef wchar_t WCHAR, *PWCHAR; What you want is std::wstring , declared in string . const PWCHAR pwc; std::wstring str(pwc); std::wstring is very similar to std::string , as both are specializations of std::basic_string ; the difference is in that wstring uses wchar_t (Windows WCHAR ), whereas string uses char .

What is the use of wchar_t?

wchar_t is used when you need to store characters with codes greater than 255 (it has a greater value than char can store). char can take 256 different values which corresponds to entries in the ISO Latin tables. On the other hand, wide char can take more than 65536 values which corresponds to Unicode values.

What is Pwstr?

7. a PWSTR would be a wchar_t string pointer. That is a UNICODE (usually UCS2) string with each character taking 16 bits. a char* would be a pointer 8 bits per character. this could be ASCII, ANSI, UTF8, or one of many hundreds of other encodings.

What is Lpstr?

LPSTR stands for “long pointer to string”. Back before 32-bit processors, pointers to memory that might be in a different segment of memory (think, a long way away in memory), needed extra space to store. On 32-bit (and later) processors, they’re exactly the same thing. Microsoft uses LPSTR solely for historic reasons.

What is Wchar support?

In other words, wchar_t is a data type which makes it possible to work with text containing characters from any language without worrying about character encoding. On platforms that support Unicode above the basic multilingual plane, wchar_t is usually 4 bytes (Linux, BSD, macOS).

What is wchar_t data type?

wchar_t is an integer type whose range of values can represent distinct codes for all members of the largest extended character set specified among the supported locales; the null character shall have the code value zero.

What is a wchar_t in C++?

wchar_t is a wide character. It is used to represent characters which require more memory to represent them than a regular char . It is, for example, widely used in the Windows API. However, the size of a wchar_t is implementation-dependant and not guaranteed to be larger than char .

What is sizeof wchar_t?

Just like the type for character constants is char, the type for wide character is wchar_t. This data type occupies 2 or 4 bytes depending on the compiler being used.

What’s the difference between a Tchar and a wchar?

TCHAR can be either char or WCHAR based on the platform. WCHAR is always a 16-bit Unicode character, wchar_t.

How is the data type defined in tchar.h?

The _TCHAR data type is defined conditionally in tchar.h. If the symbol _UNICODE is defined for your build, _TCHAR is defined as wchar_t; otherwise, for single-byte and MBCS builds, it is defined as char.

Can a Win32 string be a Tchar string?

A Win32 character string that can be used to describe ANSI, DBCS, or Unicode strings. For ANSI and DBCS platforms, TCHAR is defined as follows: For Unicode platforms, TCHAR is defined as synonymous with the WCHAR type. MAPI clients can use the TCHAR data type to represent a string of either the WCHAR or char type.

How is Tchar defined for ANSI and DBCS?

For ANSI and DBCS platforms, TCHAR is defined as follows: For Unicode platforms, TCHAR is defined as synonymous with the WCHAR type. MAPI clients can use the TCHAR data type to represent a string of either the WCHAR or char type. Be sure to define the symbolic constant UNICODE and limit the platform when it is required.
