NAMEwctob - try to represent a wide character as a single byte
#include <wchar.h> int wctob(wint_t c);
DESCRIPTIONThe 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.
RETURN VALUEThe wctob() function returns the single-byte representation of c, if it exists, of EOF otherwise.
NOTESThe behavior of wctob() depends on the LC_CTYPE category of the current locale.
This function should never be used. Internationalized programs must never distinguish single-byte and multi-byte characters. Use the function wctomb(3) instead.
