+.SH NAME

+.SH SYNOPSIS
+.LP
+.nf
+#include <wchar.h>
+.P
+int mbsinit(const mbstate_t *\fIps\fP);
+.fi
+.SH 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\(hy2017 defers to the ISO\ C standard.
+.P
+If
+.IR ps
+is not a null pointer, the
+\fImbsinit\fR()
+function shall determine whether the object pointed to by
+.IR ps
+describes an initial conversion state.
+.SH "RETURN VALUE"
+The
+\fImbsinit\fR()
+function shall return non-zero if
+.IR ps
+is a null pointer, or if the pointed-to object describes an initial
+conversion state; otherwise, it shall return zero.
+.P
+If an
+.BR 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
+.IR LC_CTYPE
+category setting than on earlier function calls, the behavior is undefined.
+.SH ERRORS
+No errors are defined.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+The
+.BR mbstate_t
+object is used to describe the current conversion state from a
+particular character sequence to a wide-character sequence (or \fIvice
+versa\fP) under the rules of a particular setting of the
+.IR LC_CTYPE
+category of the current locale.
+.P
+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
+.BR mbstate_t
+object is at least one way to describe an initial conversion state. A
+zero valued
+.BR mbstate_t
+object can be used to initiate conversion involving any character
+sequence, in any
+.IR LC_CTYPE
+category setting.
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
