Is there a function to find the length, in wide characters, of a
multibyte string? 3 2455

If you have the POSIX version of mbstowcs, you can pass it a NULL
first argument to get this number.

If you limit yourself to Standard C, I think you have to actually
perform the conversion, and then find out with wcslen().

Given that this came up when i was trying to answer someone's question
in c.u.p, this is relevant, thanks.

The reason for this was to be able to perform the conversion into memory
that is from malloc while calling malloc only once. in order to make a
wide copy of argv to pass to a "wmain"

Makes sense to me: snprintf() allows this. It's beyond me why Standard
C neglected to provide such a thing in the first place. I kind of hope
that future versions will add the POSIX behavior, as it's very useful,
and certainly not hard to implement. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hello
I've browsed the FAQ but apparently it lacks any questions concenring wide
character strings. I'd like to calculate the length of a multibyte string
without converting the whole string.
Zygmunt
PS: The whole multibyte string vs wide character string concept is broken
IMHO since it allows wchar_t not to be large enough to contain a full
character (rendering both types virtually the same). What's the point of

Is it true that
Multibyte characters are : char arrays (witch represent a string from
the basic characters set). In this case Wide characters are the way
for encoding characters from the extended characters set.
or
Multibyte characters are: characters from the extended character set
which need more than one byte to encode. And in this case wide

Hi, everyone,
I'm writing a program using wstring(wchar_t) as internal string.
The problem is raised when I convert the multibyte char set string

I have 2 ways to do the job:
