or the interface may not be implemented on Linux.
Имя (Name)
mbsinit — determine conversion object status
Синопсис (Synopsis)
#include <wchar.h>
int mbsinit(const mbstate_t *ps);
Описание (Description)
The functionality described on this reference page is aligned
with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This
volume of POSIX.1‐2017 defers to the ISO C standard.
If ps is not a null pointer, the mbsinit() function shall
determine whether the object pointed to by ps describes an
initial conversion state.
Возвращаемое значение (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 undefined.
Ошибки (Error)
No errors are defined.
The following sections are informative.
Примеры (Examples)
None.
Использование в приложениях (Application 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.
Обоснование (Rationale)
None.
