WCSTOMBS(3)              BSD Library Functions Manual              WCSTOMBS(3)

     wcstombs, wcstombs_l -- convert a wide-character string to a character string

     Standard C Library (libc, -lc)

     #include <stdlib.h>

     wcstombs(char *restrict s, const wchar_t *restrict pwcs, size_t n);

     #include <stdlib.h>
     #include <xlocale.h>

     wcstombs_l(char *restrict s, const wchar_t *restrict pwcs, size_t n, locale_t loc);

     The wcstombs() function converts a wide character string pwcs into a multibyte character string, s,
     beginning in the initial conversion state.  Up to n bytes are stored in s.  Partial multibyte charac-ters characters
     ters at the end of the string are not stored.  The multibyte character string is null terminated, if
     there is room.

     Although the wcstombs() function uses the current locale, the wcstombs_l() function may be passed a
     locale directly. See xlocale(3) for more information.

     The wcstombs() function returns the number of bytes converted (not including any terminating null), if
     successful; otherwise, it returns (size_t)-1.

     The wcstombs() function will fail if:

     [EILSEQ]           An invalid wide character was encountered.

     [EINVAL]           The conversion state is invalid.

     The wcstombs() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
