NAME

6       MB_LEN_MAX - maximum multibyte length of a character across all locales

LIBRARY

9       Standard C library (libc)

SYNOPSIS

12       #include <limits.h>

DESCRIPTION

15       The MB_LEN_MAX macro is the maximum number of bytes needed to represent
16       a single wide character, in any of the supported locales.
17

RETURN VALUE

19       A constant integer greater than zero.

NOTES

28       The entities MB_LEN_MAX and sizeof(wchar_t) are totally unrelated.   In
29       glibc,  MB_LEN_MAX  is  typically  16 (6 in glibc versions earlier than
30       2.2), while sizeof(wchar_t) is 4.
