NAME         top

       MB_LEN_MAX - maximum multibyte length of a character across all
       locales

LIBRARY         top

       Standard C library (libc)

SYNOPSIS         top

       #include <limits.h>

DESCRIPTION         top

       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         top

       A constant integer greater than zero.

STANDARDS         top

       C11, POSIX.1-2008.

HISTORY         top

       C99, POSIX.1-2001.

NOTES         top

       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.
