mbstowcs(3)              BSD Library Functions Manual              mbstowcs(3)


NAME

     mbstowcs, mbstowcs_l -- convert a character string to a wide-character
     string


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <stdlib.h>

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

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

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


DESCRIPTION

     The mbstowcs() function converts a multibyte character string s, begin-
     ning in the initial conversion state, into a wide character string pwcs.
     No more than n wide characters are stored.  A terminating null wide char-
     acter is appended, if there is room.

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


RETURN VALUES

     The mbstowcs() function returns the number of wide characters converted,
     not counting any terminating null wide character, or -1 if an invalid
     multibyte character was encountered.


ERRORS

     The mbstowcs() function will fail if:

     [EILSEQ]           An invalid multibyte sequence was detected.

     [EINVAL]           The conversion state is invalid.
