Is there a function to find the length, in wide characters, of a
multibyte string? 3 2431

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
