Please, how can I find out the length of a variable of type wchar_t*
in c++?
code example below:
wchar_t* dimObjPrefix = L"retro_";
I would like to find out how many characters dimObjPrefix
contains
如果你想知道wchar_t
字符串( wchar_t *
)的大小,你想使用wcslen(3)
:
size_t wcslen (const wchar_t *ws);
Assuming that you want to get the length of null terminated C style string, you have two options:
#include <cwchar>
and use std::wcslen (dimObjPrefix);
, #include <string>
and use std::char_traits<wchar_t>::length (dimObjPrefix);
.
