DESCRIPTION

25       These functions operate on Process Code strings terminated  by  wchar_t
26       null  characters.   During  appending or copying, these routines do not
27       check for an overflow condition of the receiving string. In the follow‐
28       ing,  s,  s1,  and  s2  point  to  Process Code strings terminated by a
29       wchar_t null.
30
31   wscasecmp(), wsncasecmp()
32       The wscasecmp() function compares its  arguments,  ignoring  case,  and
33       returns  an  integer  greater than, equal to, or less than 0, depending
34       upon whether s1 is lexicographically greater than, equal  to,  or  less
35       than  s2.  It  makes the same comparison but compares at most n Process
36       Code characters. The four Extended Unix Code (EUC) codesets are ordered
37       from  lowest  to  highest  as 0, 2, 3, 1 when characters from different
38       codesets are compared.
39
40   wsdup()
41       The wsdup() function returns a pointer to a new  Process  Code  string,
42       which  is  a duplicate of the string pointed to by s. The space for the
43       new string is obtained using malloc(3C). If the new  string  cannot  be
44       created, a null pointer is returned.
45
46   wscol()
47       The  wscol()  function returns the screen display width (in columns) of
48       the Process Code string s.
