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

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

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

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

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

DESCRIPTION
     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 characters 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.

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

ERRORS
     The wcstombs() function will fail if:

     [EILSEQ]		An invalid wide character was encountered.

     [EINVAL]		The conversion state is invalid.

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