I am using std::wstring
as my Unicode style string. Now I want to get the
byte size of a wstring
.
If I use size()
method of wstring
, I just get the total number of chars
in my wstring
. But the byte should be size() * 2.
Is there an official way to get this byte size? I don't want to use
size() * 2 in my program.....
I want to use in RegSetValueExW
as last parameter.
Use str.size() * sizeof(wchar_t)
or equivalent.
In fact, I can't think of any other platform besides Windows that has 2-byte wchar_t
, 4 bytes is far more common.
