WCTOB(3) Linux Programmer's Manual WCTOB(3)NAMEwctob - try to represent a wide character as a single byte
int wctob(wint_t c);
The wctob() function tests whether the multibyte representation of the
wide character c, starting in the initial state, consists of a single
byte. If so, it is returned as an unsigned char.
Never use this function. It cannot help you in writing international‐
ized programs. Internationalized programs must never distinguish sin‐
gle-byte and multibyte characters.
The wctob() function returns the single-byte representation of c, if it
exists, of EOF otherwise.
The behavior of wctob() depends on the LC_CTYPE category of the current
This function should never be used. Internationalized programs must
never distinguish single-byte and multibyte characters. Use either
wctomb(3) or the thread-safe wcrtomb(3) instead.
