  11 .TH WCTOB 3C "Jun 25, 2014"
  12 .SH NAME
  13 wctob, wctob_l \- wide-character to single-byte conversion
  14 .SH SYNOPSIS
  15 .LP
  16 .nf
  17 #include <stdio.h>
  18 #include <wchar.h>
  19 
  20 \fBint\fR \fBwctob\fR(\fBwint_t\fR \fIc\fR);

  22 .LP
  23 .nf
  24 #include <stdio.h>
  25 #include <wchar.h>
  26 #include <xlocale.h>
  27 
  28 \fBint\fR \fBwctob_l\fR(\fBwint_t\fR \fIc\fR, \fBlocale_t\fR \fIloc\fR);
  29 .fi
  30 .SH DESCRIPTION
  31 .LP
  32 The \fBwctob()\fR function determines whether \fIc\fR corresponds to a member
  33 of the extended character set whose  character representation is a single byte
  34 when in the initial shift state.
  35 .LP
  36 The behavior of \fBwctob()\fR is affected by the \fBLC_CTYPE\fR category of the
  37 current locale.  See \fBenviron\fR(5)
  38 .LP
  39 The function \fBwctob_l()\fR behaves identically to \fBwctob()\fR, except
  40 instead of operating in the current locale, it operates in the locale
  41 specified by \fIloc\fR.
  42 .SH RETURN VALUES
  43 .LP
  44 These functions return \fBEOF\fR if \fIc\fR does not correspond to
  45 a character with length one in the initial shift state.  Otherwise, they return
  46 the single-byte representation of that character.
  47 .SH ERRORS
  48 .LP
  49 No errors are defined.
