  22 .SH DESCRIPTION
  23 .sp
  24 .LP
  25 The \fBwctomb()\fR function determines the number of bytes needed to represent
  26 the character corresponding to the wide-character code whose value is
  27 \fIwchar\fR. It stores the character representation (possibly multiple bytes)
  28 in the array object pointed to by \fIs\fR (if \fIs\fR is not a null pointer).
  29 At most \fBMB_CUR_MAX\fR bytes are stored.
  30 .sp
  31 .LP
  32 A call with \fIs\fR as a null pointer causes this function to return \fB0\fR.
  33 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
  34 current locale.
  35 .sp
  36 .LP
  37 The function \fBwctomb_l()\fR behaves identically to \fBwctomb()\fR, except
  38 instead of operating in the current environemtn, it operates in the environment
  39 specified by \fIloc\fR.
  40 .SH RETURN VALUES
  41 .sp
  42 .LP
  43 If \fIs\fR is a null pointer, \fBwctomb()\fR returns \fB0\fR value. If \fIs\fR
  44 is not a null pointer, \fBwctomb()\fR returns \fB\(mi1\fR if the value of
  45 \fIwchar\fR does not correspond to a valid character, or returns the number of
  46 bytes that constitute the character corresponding to the value of \fIwchar\fR.
  47 .sp
  48 .LP
  49 In no case will the value returned be greater than the value of the
  50 \fBMB_CUR_MAX\fR macro.
  51 .SH ERRORS
  52 .sp
  53 .LP
  54 No errors are defined.
  55 .SH USAGE
  56 .sp
  57 .LP
  58 The \fBwctomb()\fR function can be used safely in a multithreaded application,
  59 as long as \fBsetlocale\fR(3C) is not being called to change the locale.
