wctob - try to represent a wide character as a single byte
int wctob(wint_t c);
The wctob() function tests whether the multi-byte 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 multi-byte 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 multi-byte characters. Use the func-
tion wctomb(3) instead.
