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. ATTRIBUTES

The mbsinit() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the locale. SunOS 5.11 24 Jul 2002 mbsinit(3C)

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 shall determine whether the object pointed to by ps describes an initial conversion state. RETURN VALUE
The mbsinit() function shall return non-zero if ps is a null pointer, or if the pointed-to object describes an initial conversion state; otherwise, it shall return zero. 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. ERRORS
