       wcstombs - convert a wide-character string to a multibyte string

       #include <stdlib.h>

       size_t wcstombs(char *dest, const wchar_t *src, size_t n);

       If  dest is not NULL, the wcstombs() function converts the wide-charac‐
       ter string src to a multibyte string starting at dest.  At most n bytes
       are  written to dest.  The conversion starts in the initial state.  The
       conversion can stop for three reasons:

       1. A wide character has been encountered that can not be represented as
       a  multibyte sequence (according to the current locale).	 In this case,
       (size_t) -1 is returned.

       2. The length limit forces a stop.  In this case, the number  of	 bytes
       written to dest is returned, but the shift state at this point is lost.

       3.  The	wide-character string has been completely converted, including
       the terminating null wide character (L'\0').  In this case, the conver‐
       sion  ends  in the initial state.  The number of bytes written to dest,
       excluding the terminating null byte ('\0'), is returned.

       The programmer must ensure that there is room for at least n  bytes  at

       If  dest	 is  NULL, n is ignored, and the conversion proceeds as above,
       except that the converted bytes are not written out to memory,  and  no
       length limit exists.

       In  order  to avoid the case 2 above, the programmer should make sure n
       is greater than or equal to wcstombs(NULL,src,0)+1.

       The wcstombs() function returns the number of bytes that	 make  up  the
       converted  part	of a multibyte sequence, not including the terminating
       null byte.  If a wide character was encountered which could not be con‐
       verted, (size_t) -1 is returned.


       The behavior of wcstombs() depends on the LC_CTYPE category of the cur‐
       rent locale.

       The function wcsrtombs(3) provides a thread safe interface to the  same

       mblen(3), mbtowc(3), mbstowcs(3), wcsrtombs(3) wctom(3)
