#include <stdlib.h>
int wctomb(char *string, wchar_t character);Converts the wchar_t value of character into a multibyte array pointed to by string. If the value of character is 0, the function is left in the initial shift state. At most, wctomb() stores MB_CUR_MAX characters in string.
The behavior of this wide-character function is affected by the LC_CTYPE category of the current locale. If you change the category, undefined results can occur.
If successful, wctomb() returns the length in bytes of the multibyte character.
If character is not a valid multibyte character, wctomb() returns -1.
If string is a NULL pointer, wctomb() returns nonzero if shift-dependent encoding is used, or 0 otherwise.

This example converts the wide character c to a character using wctomb().

length = wctomb( buffer, wch );

} The number of bytes that comprise the multibyte character is 1
And the converted string is "c"
