wctomb(3int)							  wctomb(3int)

Name
       wctomb - converts a character of type wchar_t to a multibyte character.

Syntax
       #include <stdlib.h>

       int wctomb (s, wchar)
       char *s;
       wchar_t wchar;

Arguments
       s       The  s argument is a pointer to the resulting multibyte charac‐
	       ter object.

       wchar   The wchar argument is a value of type wchar_t.

Description
       The function determines the number of bytes  needed  to	represent  the
       multibyte character corresponding to the character code of type wchar_t
       whose value is wchar.  It stores the multibyte character representation
       in  the	array object pointed to by s (if s is not a null pointer).  At
       most MB_CUR_MAX characters are stored.  This function  is  affected  by
       the LC_CTYPE category of the current locale.

Return Value
       If s is a null pointer, the function returns a zero value.  If s is not
       a null pointer, the function returns:

	  ·  - -1, if the value of wchar does not correspond to a valid multi‐
	     bye character

	  ·  The  number of bytes that comprise the multibyte character corre‐
	     sponding to the value of wchar.  In no case is the value returned
	     greater than the value of the MB_CUR_MAX macro.
