  22 .SH DESCRIPTION
  23 .sp
  24 .LP
  25 If \fBps\fR is not a null pointer, the \fBmbsinit()\fR function determines
  26 whether the object pointed to by \fBps\fR describes an initial conversion state.
  27 the function \fBmbsinit_l()\fR behaves identically to \fBmbsinit()\fR except the

  28 current locale is ignored and the locale \fIloc\fR is used instead.
  29 .SH RETURN VALUES
  30 .sp
  31 .LP
  32 The \fBmbsinit()\fR function returns non-zero if  \fBps\fR is a null pointer,
  33 or if the pointed-to object describes an initial conversion state; otherwise,
  34 it returns \fB0\fR.
  35 .sp
  36 .LP
  37 If an \fBmbstate_t\fR object is altered by any of the functions described as
  38 "restartable", and is then used with a different character sequence, or in the
  39 other conversion direction, or with a different \fBLC_CTYPE\fR category setting
  40 than on earlier function calls, the behavior is undefined.  See
  41 \fBenviron\fR(5).
  42 .SH ERRORS
  43 .sp
  44 .LP
  45 No errors are defined.
  46 .SH USAGE
  47 .sp
  48 .LP
  49 The \fBmbstate_t\fR object is used to describe the current conversion state
  50 from a particular character sequence to a wide-character sequence (or vice
  51 versa) under the rules of a particular setting of the \fBLC_CTYPE\fR category
  52 of the current locale.
  53 .sp
  54 .LP
  55 The initial conversion state corresponds, for a conversion in either direction,
  56 to the beginning of a new character sequence in the initial shift state.  A
  57 zero-valued \fBmbstate_t\fR object is at least one way to describe an initial
  58 conversion state.  A zero-valued \fBmbstate_t\fR object can be used to initiate
  59 conversion involving any character sequence, in any \fBLC_CTYPE\fR category
  60 setting.

  87 .LP
  88 The \fBmbsinit()\fR function can be used safely in multithreaded applications,
  89 as long as \fBsetlocale\fR(3C) is not being called to change the locale or a
  90 per-thread locale has been installed with \fBuselocale\fR(3C).
