mbsinit(3C)              Standard C Library Functions              mbsinit(3C)

NAME
       mbsinit - determine conversion object status

SYNOPSIS
       #include <wchar.h>

       int mbsinit(const mbstate_t *ps);

DESCRIPTION
       If  ps is not a null pointer, the mbsinit() function determines whether
       the object pointed to by ps describes an initial conversion state.

RETURN VALUES
       The mbsinit() function returns non-zero if ps is a null pointer, or  if
       the pointed-to object describes an initial conversion state; otherwise,
       it returns 0.


       If  an mbstate_t object is altered by any of the functions described as
       "restartable", and is then used with a different character sequence, or
       in the other conversion direction, or with a different  LC_CTYPE  cate‐
       gory setting than on earlier function calls, the behavior is undefined.
       See environ(7).

ERRORS
       No errors are defined.

USAGE
       The  mbstate_t  object is used to describe the current conversion state
       from a particular character sequence to a wide-character  sequence  (or
       vice  versa)  under  the  rules of a particular setting of the LC_CTYPE
       category of the current locale.


       The initial conversion state corresponds, for a  conversion  in  either
       direction,  to the beginning of a new character sequence in the initial
       shift state. A zero-valued mbstate_t object is at least one way to  de‐
       scribe  an initial conversion state. A zero-valued mbstate_t object can
       be used to initiate conversion involving any character sequence, in any
       LC_CTYPE category setting.
