MB_LEN_MAX — maximum multibyte length of a character
across all locales
Synopsis
#include <limits.h>
DESCRIPTION
The MB_LEN_MAX macro is the
upper bound for the number of bytes needed to represent a
single wide character, in any of the supported locales.
RETURN VALUE
A constant integer greater than zero.
CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99.
NOTES
The entities MB_LEN_MAX and
sizeof(wchar_t) are
totally unrelated. In glibc, MB_LEN_MAX is typically 16 (6 in glibc
versions earlier than 2.2) while sizeof(wchar_t) is 4.
