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. 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.
