MBSINIT(3)						   BSD Library Functions Manual 						MBSINIT(3)

NAME

     mbsinit -- determines whether the state object is in the initial state

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <wchar.h>

     int
     mbsinit(const mbstate_t *ps);

DESCRIPTION

     The mbsinit() determines whether the state object pointed to by ps is the initial conversion state, or not.

     ps may be a null pointer.	In this case, mbsinit() will always return non-zero.

RETURN VALUES

     mbsinit() returns:

     0		 The current state is not the initial state.

     non-zero	 The current state is the initial state or ps is a null pointer.

ERRORS

     No errors are defined.

STANDARDS

     The mbsinit() conforms to ISO/IEC 9899/AMD1:1995 (``ISO C90, Amendment 1'').

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; other-
       wise, 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 category setting than on earlier function calls, the behavior is unde-
       fined.  See environ(5).

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 describe 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.

NOTES

       The mbsinit() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale.
