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, across
       all locales.


RETURN VALUE

       A constant integer >= 1.


CONFORMING TO

       ANSI C, POSIX.1


NOTES

       The entities MB_LEN_MAX and  sizeof(wchar_t)  are  totally
       unrelated.  In  the  GNU  libc,  MB_LEN_MAX is typically 6
       while sizeof(wchar_t) is 4.
