PROLOG

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

NAME

       wcscmp -- compare two wide-character strings

SYNOPSIS

       #include <wchar.h>

       int wcscmp(const wchar_t *ws1, const wchar_t *ws2);

DESCRIPTION

       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.1-2008 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-charac-
       ter codes that differ in the objects being compared.

RETURN VALUE

       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.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

NAME

       wcscspn -- get the length of a complementary wide substring

SYNOPSIS

       #include <wchar.h>

       size_t wcscspn(const wchar_t *ws1, const wchar_t *ws2);

DESCRIPTION

       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.1-2008 defers to the ISO C standard.

       The wcscspn() function shall compute the length (in wide characters) of the maximum initial segment of the wide-character string pointed to
       by ws1 which consists entirely of wide-character codes not from the wide-character string pointed to by ws2.

RETURN VALUE

       The wcscspn() function shall return the length of the initial substring of ws1; no return value is reserved to indicate an error.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
