MB_LEN_MAX(3)		   Linux Programmer's Manual		 MB_LEN_MAX(3)



NAME
       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.
