MBSTOWCS(3)           DragonFly 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 wcstring, const char * restrict mbstring, size_t nwchars); #include <xlocale.h> size_t mbstowcs_l(wchar_t * restrict wcstring, const char * restrict mbstring, size_t nwchars, locale_t locale);

DESCRIPTION

The mbstowcs() and mbstowcs_l() functions convert a multibyte character string mbstring beginning in the initial conversion state into a wide character string wcstring. No more than nwchars wide characters are stored. A terminating null wide character is appended if there is room. The mbstowcs_l() function takes an explicit locale argument, whereas the mbstowcs() function uses the current global or per-thread locale.

RETURN VALUES

The mbstowcs() and mbstowcs_l() functions return 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() and mbstowcs_l() functions will fail if: [EILSEQ] An invalid multibyte sequence was detected. [EINVAL] The conversion state is invalid.
