.SH DESCRIPTION
|
||
|
The
|
||
|
.B MB_LEN_MAX
|
||

macro is the upper bound for the number of bytes needed to represent a single
|
||
|
wide character, across all locales.

.SH NOTES
|
||
|
The entities
|
||
|
.B MB_LEN_MAX
|
||
|
and
|
||
|
.B sizeof(wchar_t)
|
||
|
are totally unrelated. In the GNU libc,
|
||
|
.B MB_LEN_MAX
|
||
|
is typically 6 while
|
||
|
.B sizeof(wchar_t)
|
||
|
is 4.
