  11 .SH NAME
  12 wctob \- wide-character to single-byte conversion
  13 .SH SYNOPSIS

  22 .SH DESCRIPTION
  23 .sp
  24 .LP
  25 The \fBwctob()\fR function determines whether \fIc\fR corresponds to a member
  26 of the extended character set whose  character representation is a single byte
  27 when in the initial shift state.
  28 .sp
  29 .LP
  30 The behavior of this function is affected by the \fBLC_CTYPE\fR category of the
  31 current locale.  See \fBenviron\fR(5)




  32 .SH RETURN VALUES
  33 .sp
  34 .LP
  35 The \fBwctob()\fR function returns \fBEOF\fR if \fIc\fR does not correspond to
  36 a character with length one in the initial shift state.  Otherwise, it returns
  37 the single-byte representation of that character.

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

  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.
