mbsnrtowcs
POSIX specification:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/mbsnrtowcs.html
Gnulib module: mbsnrtowcs
Portability problems fixed by Gnulib:
(size_t) -1
and set errno
to EILSEQ
:
glibc 2.35.
Portability problems not fixed by Gnulib:
wchar_t
is a 16-bit type and
therefore cannot accommodate all Unicode characters.
However, the Gnulib function mbsnrtoc32s
, provided by Gnulib module
mbsnrtoc32s
, operates on 32-bit wide characters and therefore does not
have this limitation.
