  32 .SH DESCRIPTION
  33 .sp
  34 .LP
  35 These functions operate on Process Code strings terminated by \fBwchar_t\fR
  36 null characters.  During appending or copying, these routines do not check for
  37 an overflow condition of the receiving string. In the following, \fIs\fR,
  38 \fIs1\fR, and \fIs2\fR point to Process Code strings terminated by a
  39 \fBwchar_t\fR null.
  40 .SS "wscasecmp(\|), wsncasecmp(\|)"
  41 .sp
  42 .LP
  43 The \fBwscasecmp()\fR function compares its arguments, ignoring case, and
  44 returns an integer greater than, equal to, or less than 0, depending upon
  45 whether \fIs1\fR is lexicographically greater than, equal to, or less than
  46 \fIs2\fR. It makes the same comparison but compares at most \fIn\fR Process
  47 Code characters. The four Extended Unix Code (EUC) codesets are ordered from
  48 lowest to highest as 0, 2, 3, 1 when characters from different codesets are
  49 compared.
  50 .SS "wsdup(\|)"
  51 .sp
  52 .LP
  53 The \fBwsdup()\fR function returns a pointer to a new Process Code string,
  54 which is a duplicate of the string pointed to by \fIs\fR. The space for the new
  55 string is obtained using \fBmalloc\fR(3C). If the new string cannot be created,
  56 a null pointer is returned.
  57 .SS "wscol(\|)"
  58 .sp
  59 .LP
  60 The \fBwscol()\fR function returns the screen display width (in columns) of the
  61 Process Code string \fIs\fR.

  47 .Sh DESCRIPTION
  48 These functions operate on wide-character strings. They are the historical
  49 functions for performing operation on such strings, and have been superseded
  50 by newer functions by various standards bodies.  As such, their use is
  51 deprecated and should be avoided in new applications.
  52 .Lp
  53 Wide-character strings
  54 .Fa s1 ,
  55 .Fa s2 ,
  56 and
  57 .Fa s
  58 used in these functions are terminated by
  59 null wide-characters.  None of these functions check for overflow
  60 conditions when appending to or copying strings.
  61 .
  62 .Ss Fn wscasecmp , wsncasecmp
  63 The
  64 .Fn wscasecmp
  65 and
  66 .Fn wsncasecmp
  67 functions compares their arguments, ignoring differences in case according
  68 to the current locale.  Whereas
  69 .Fn wscasecmp
  70 continues comparing the strings until either a difference is found,
  71 or the end of either string is reached, the
  72 .Fn wcsncasecmp
  73 function compares at most
  74 .Fa n
  75 wide-characters.
  76 .Lp
  77 The
  78 .Fn wscasecmp
  79 and
  80 .Fn wsncasecmp
  81 functions have been superseded by
  82 .Xr wcscasecmp 3C
  83 and
  84 .Xr wcsncasecmp 3C ,
  85 respectively, and behave identically to them.
  86 .Lp
  87 Note that for lexigraphic comparisions, the four Extended Unix Code (EUC)
  88 character sets are ordered from lowest to highest.
  89 .
  90 .Ss Fn wscol
  91 .
  92 The
  93 .Fn wscol
  94 function returns the width in screen columns required to display the
  95 wide-character string
  96 .Fa s .
  97 This function has been superseded by
  98 .Xr wcswidth
  99 and behaves similarily to it.
 100 .
 101 .Ss Fn wsdup
 102 .
 103 The
 104 .Fn wsdup
 105 returns a duplicate copy of the wide-character string
 106 .Fa s .
 107 This function has been superseded by
 108 .Xr wcsdup 3C ,
 109 and behaves identically to it.
 110 .
 111 .Ss Fn wslen
 112 .
 113 The
 114 .Fn wslen
 115 function returns the number of wide-characters in
 116 .Fa s ,
 117 excluding the terminating null wide-character code.  This function has been
 118 superseded by
 119 .Xr wcslen 3C ,
 120 and behaves identically to it.
