.SH NAME
mbsinit,mbsinit_l \- determine conversion object status
.SH SYNOPSIS
.LP
.nf
#include <wchar.h>
\fBint\fR \fBmbsinit\fR(\fBconst mbstate_t *\fR\fIps\fR);
.fi
.LP
.nf
#include <wchar.h>
#include <xlocale.h>
\fBint\fR \fBmbsinit_l\fR(\fBconst mbstate_t *\fR\fIps\fR, \fBlocale_t\fR \fIloc\fR);
.fi
.SH DESCRIPTION
.LP
If \fBps\fR is not a null pointer, the \fBmbsinit()\fR function determines
whether the object pointed to by \fBps\fR describes an initial conversion state.
.LP
The function \fBmbsinit_l()\fR behaves identically to \fBmbsinit()\fR except the
current locale is ignored and the locale \fIloc\fR is used instead.
.SH RETURN VALUES
.LP
The \fBmbsinit()\fR function returns non-zero if \fBps\fR is a null pointer,
or if the pointed-to object describes an initial conversion state; otherwise,
it returns \fB0\fR.
.LP
If an \fBmbstate_t\fR 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 \fBLC_CTYPE\fR category setting
than on earlier function calls, the behavior is undefined. See
\fBenviron\fR(5).
.SH ERRORS
.LP
No errors are defined.
.SH USAGE
.LP
The \fBmbstate_t\fR 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 \fBLC_CTYPE\fR category
of the current locale.
.LP
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 \fBmbstate_t\fR object is at least one way to describe an initial
conversion state. A zero-valued \fBmbstate_t\fR object can be used to initiate
conversion involving any character sequence, in any \fBLC_CTYPE\fR category
setting.
