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, beginning in the initial conversion state, into a wide character string
     pwcs.  No more than n wide characters are stored.	A terminating null wide character 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.

STANDARDS

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