  11 .TH WCTOMB 3C "Jun 25, 2014"
  12 .SH NAME
  13 wctomb, wctomb_l \- convert a wide-character code to a character
  14 .SH SYNOPSIS
  15 .LP
  16 .nf
  17 #include <stdlib.h>
  18 
  19 \fBint\fR \fBwctomb\fR(\fBchar *\fR\fIs\fR, \fBwchar_t\fR \fIwchar\fR);
  20 .fi
  21 .LP
  22 .nf
  23 #include <stdlib.h>
  24 #include <xlocale.h>
  25 
  26 \fBint\fR \fBwctomb_l\fR(\fBchar *\fR\fIs\fR, \fBwchar_t\fR \fIwchar\fR, \fBlocale_t\fR \fIloc\fR);
  27 .fi
  28 .SH DESCRIPTION
  29 .LP
  30 The \fBwctomb()\fR function determines the number of bytes needed to represent
  31 the character corresponding to the wide-character code whose value is
  32 \fIwchar\fR. It stores the character representation (possibly multiple bytes)
  33 in the array object pointed to by \fIs\fR (if \fIs\fR is not a null pointer).
  34 At most \fBMB_CUR_MAX\fR bytes are stored.
  35 .LP
  36 A call with \fIs\fR as a null pointer causes this function to return \fB0\fR.
  37 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
  38 current locale.
  39 .LP
  40 The function \fBwctomb_l()\fR behaves identically to \fBwctomb()\fR, except
  41 instead of operating in the current locale, it operates in the locale
  42 specified by \fIloc\fR.
  43 .SH RETURN VALUES
  44 .LP
  45 If \fIs\fR is a null pointer, \fBwctomb()\fR returns \fB0\fR value. If \fIs\fR
  46 is not a null pointer, \fBwctomb()\fR returns \fB\(mi1\fR if the value of
  47 \fIwchar\fR does not correspond to a valid character, or returns the number of
  48 bytes that constitute the character corresponding to the value of \fIwchar\fR.
  49 .LP
  50 In no case will the value returned be greater than the value of the
  51 \fBMB_CUR_MAX\fR macro.
  52 .SH ERRORS
  53 .LP
  54 No errors are defined.
