    Command:

    wcscoll

    
    
    

    SYNOPSIS

           #include <wchar.h>
    
           int wcscoll(const wchar_t *ws1, const wchar_t *ws2);
    
    
    

    DESCRIPTION

           The  wcscoll() function shall compare the wide-character string pointed
           to by ws1 to the wide-character string pointed to by ws2,  both  inter-
           preted as appropriate to the LC_COLLATE category of the current locale.
    
           The wcscoll() function shall not change the setting of  errno  if  suc-
           cessful.
    
           An  application  wishing to check for error situations should set errno
           to 0 before calling wcscoll(). If errno is non-zero on return, an error
           has occurred.
    
    
    

    RETURN VALUE

           Upon  successful  completion, wcscoll() shall return an integer greater
           than, equal to, or less than 0, according to whether the wide-character
           string  pointed  to  by ws1 is greater than, equal to, or less than the
           wide-character string pointed to by ws2, when both are  interpreted  as
           appropriate  to  the  current  locale.    On error, wcscoll() shall set
           errno, but no return value is reserved to indicate an error.
    
    
    

    ERRORS

           The wcscoll() function may fail if:
    
           EINVAL The ws1 or ws2 arguments contain  wide-character  codes  outside
                  the domain of the collating sequence.
