wstring(3C)

NAME

     wstring, wscasecmp, wsncasecmp, wsdup, wscol - Process  Code
     string operations

SYNOPSIS

     #include <widec.h>

     int wscasecmp(const wchar_t *s1, const wchar_t *s2);

     int wsncasecmp(const wchar_t *s1, const wchar_t *s2, int n);

     wchar_t *wsdup(const wchar_t *s);

     int wscol(const wchar_t *s);

DESCRIPTION

     These functions operate on Process Code  strings  terminated
     by  wchar_t  null  characters.  During appending or copying,
     these routines do not check for an overflow condition of the
     receiving  string.  In the following, s, s1, and s2 point to
     Process Code strings terminated by a wchar_t null.

  wscasecmp(), wsncasecmp()
     The wscasecmp() function compares  its  arguments,  ignoring
     case, and returns an integer greater than, equal to, or less
     than 0,  depending  upon  whether  s1  is  lexicographically
     greater  than,  equal to, or less than s2. It makes the same
     comparison but compares at most n Process  Code  characters.
     The  four Extended Unix Code (EUC) codesets are ordered from
     lowest to highest as 0, 2, 3, 1 when  characters  from  dif-
     ferent codesets are compared.

  wsdup()
     The wsdup() function returns a pointer to a new Process Code
     string,  which is a duplicate of the string pointed to by s.
     The space for the new string is obtained  using  malloc(3C).
     If  the  new  string  cannot  be  created, a null pointer is
     returned.

  wscol()
     The wscol() function returns the screen  display  width  (in
     columns) of the Process Code string s.
