 .SH NAME
-mbsinit \- determine conversion object status
+mbsinit,mbsinit_l \- determine conversion object status
 .SH SYNOPSIS

 #include <wchar.h>
 
 \fBint\fR \fBmbsinit\fR(\fBconst mbstate_t *\fR\fIps\fR);
 .fi

+.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
-.sp
 .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.
+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
-.sp
 .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.
-.sp
 .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
-.sp
 .LP
 No errors are defined.
 .SH USAGE
-.sp
 .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.
-.sp
 .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.

-The \fBmbsinit()\fR function can be used safely in multithreaded applications,
-as long as \fBsetlocale\fR(3C) is not being called to change the locale.
