wctomb —
#include <stdlib.h>
int
  
  wctomb(char
    * s, wchar_t
    wchar);
wctomb() converts the wide character
  wchar to the corresponding multibyte character, and
  stores it in the array pointed to by s.
  wctomb() may store at most
  MB_CUR_MAX bytes in the array.
In state-dependent encoding, wctomb() may
    store the special sequence to change the conversion state before an actual
    multibyte character into the array pointed to by s. If
    wchar is a nul wide character (‘\0’),
    this function sets its own internal state to an initial conversion
  state.
Calling any other functions in Standard
    C Library (libc, -lc) never changes the internal state of
    wctomb(), except changing the
    LC_CTYPE category of the current locale by calling
    setlocale(3). Such
    setlocale(3) calls cause
    the internal state of this function to be indeterminate.
The behaviour of wctomb() is affected by
    the LC_CTYPE category of the current locale.
There is one special case:
wctomb() initializes its own internal state to an
      initial state, and determines whether the current encoding is
      state-dependent. This function returns 0 if the encoding is
      state-independent, otherwise non-zero. In this case,
      wchar is completely ignored.wctomb() returns:
MB_CUR_MAX macro.If s is equal to
    NULL, wctomb() returns:
wctomb() function conforms to ANSI
  X3.159-1989 (“ANSI C89”).
