MB_LEN_MAX(3)

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

LIBRARY
Standard C library (libc)

SYNOPSIS
#include <limits.h>

DESCRIPTION
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
A constant integer greater than zero.

STANDARDS
C11, POSIX.1-2008.

HISTORY
C99, POSIX.1-2001.

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.
