sizeof wchar_t. Unlike Windows UTF-16 2-byte wide chars, wchar_t on Linux and OS X is 4 bytes UTF-32 (gcc/g++ and XCode). On cygwin it is 2 (cygwin uses Windows APIs). At first I used runtime if statements like if ( sizeof(wchar_t) == 4 ) but aside from being bad style that led to compiler warnings in the code that was for the other size of wchar_t.
This intrigues me, so I’m going to ask – for what reason is wchar_t not used so widely on Linux / Linux -like systems as it is on Windows? Specifically, the Windows API uses wchar_t internally whereas I believe Linux does not and this is reflected in a number of open source packages using char types.. My understanding is that given a character c which requires multiple bytes to represent it, then …
12/17/2020 · Note that on AIX and Linux PPC a long double is 8 bytes. pointer: 8 bytes: ptrdiff_t: 8 bytes: size_t: 8 bytes: time_t: 8 bytes: clock_t: 8 bytes . Note that on the other UNIX platform a clock_t is 4 bytes. wchar_t: 4 bytes . Note that on AIX a wchar_t is 2 bytes.
Author: Leslie P. Polzer The ISO C90 standard introduced a wide character type named wchar_t , thereby appointing an official standard for wide characters in the C language. Its usage, however, is not well understood among C programmers, and debugging wide characters with the GNU Debugger is a challenge few can get to work. As a […], The wcscmp() function is the wide-character equivalent of the strcmp(3) function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2.

Wide char and library functions in C++ – GeeksforGeeks, 3/10/2012 · You are free to use char and wchar_t , and project settings will not affect any direct use of these keywords. T CHAR is defined as: #ifdef _UNICODE typedef wchar_t TCHAR; #else typedef char TCHAR; #endif. The macro _UNICODE is defined when you set Character Set to Use Unicode Character Set, and therefore TCHAR would mean wchar_t .
The wcslen() function is the wide-character equivalent of the strlen(3) function. It determines the length of the wide-character string pointed to by s , excluding the terminating null wide character (L’ ’).

5/21/2017 · wcscpy() : syntax: wchar_t *wcscpy(wchar_t *strDestination, const wchar_t *strSource); wcscpy() stands for Wide-Character String Copy. It copies a wide-character string pointed by strSource into the wide character array pointed by strDestination. This is the wide character equivalent of strcpy.
