Synopsis
#include <limits.h>
Description
The
MB_LEN_MAX macro is the maximum number of bytes needed to represent a single wide character, in any of the supported locales.
Return Value
A constant integer greater than zero.

The entities
MB_LEN_MAX and
sizeof(wchar_t) are totally unrelated. In glibc,
