       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2017 defers to the ISO C standard.

       The  wcscmp()  function  shall  compare the wide-character string pointed to by ws1 to the wide-character
       string pointed to by ws2.

       The sign of a non-zero return value shall be determined by the sign of the difference between the  values
       of the first pair of wide-character codes that differ in the objects being compared.

       No errors are defined.

       wcscmp — compare two wide-character strings

       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of this interface
       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.

       None.

       Upon  completion,  wcscmp()  shall return an integer greater than, equal to, or less than 0, if the wide-
       character string pointed to by ws1 is greater than, equal to, or  less  than  the  wide-character  string
       pointed to by ws2, respectively.
