MB_LEN_MAX ? maximum multibyte length of a character across all locales |
#include <limits.h> |
The MB_LEN_MAX macro is the upper bound for the number of bytes needed to represent a single wide character, across all locales. |
A constant integer >= 1. |
ANSI C, POSIX.1 |
The entities MB_LEN_MAX and sizeof(wchar_t) are totally unrelated. In the GNU libc, MB_LEN_MAX is typically 6 while sizeof(wchar_t) is 4. |
