#include <wchar.h>
wint_t
btowc(int c);
int
wctob(wint_t c);
DESCRIPTION
The btowc() function converts a single-byte character into a correspond‐
ing wide character. If the character is EOF or not valid in the initial
shift state, btowc() returns WEOF.
The wctob() function converts a wide character into a corresponding sin‐
gle-byte character. If the wide character is WEOF or not able to be rep‐
resented as a single byte in the initial shift state, wctob() returns
WEOF.
