10.46.33 mbstowcs ¶
POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/mbstowcs.html
Gnulib module: mbstowcs
Portability problems fixed by Gnulib:
- In the C or POSIX locales, this function can return
(size_t) -1
and set errno to EILSEQ:
glibc 2.35.
Portability problems not fixed by Gnulib:
- On Windows and 32-bit AIX platforms,
wchar_t is a 16-bit type and
therefore cannot accommodate all Unicode characters.
However, the Gnulib function mbstoc32s, provided by Gnulib module
mbstoc32s, operates on 32-bit wide characters and therefore does not
have this limitation.
