+.SH DESCRIPTION
+The
+\fIwcscasecmp\fR()
+and
+\fIwcsncasecmp\fR()
+functions are the wide-character equivalent of the
+\fIstrcasecmp\fR()
+and
+\fIstrncasecmp\fR()
+functions, respectively.
+.P
+The
+\fIwcscasecmp\fR()
+and
+\fIwcscasecmp_l\fR()
+functions shall compare, while ignoring differences in case, the
+wide-character string pointed to by
+.IR ws1
+to the wide-character string pointed to by
+.IR ws2 .
+.P
+The
+\fIwcsncasecmp\fR()
+and
+\fIwcsncasecmp_l\fR()
+functions shall compare, while ignoring differences in case, not more
+than
+.IR n
+wide-characters from the wide-character string pointed to by
+.IR ws1
+to the wide-character string pointed to by
+.IR ws2 .
+.P
+The
+\fIwcscasecmp\fR()
+and
+\fIwcsncasecmp\fR()
+functions use the current locale to determine the case of the wide
+characters.
+.P
+The
+\fIwcscasecmp_l\fR()
+and
+\fIwcsncasecmp_l\fR()
+functions use the locale represented by
+.IR locale
+to determine the case of the wide characters.
+.P
+When the
+.IR LC_CTYPE
+category of the locale being used is from the POSIX locale, these
+functions shall behave as if the wide-character strings had been converted
+to lowercase and then a comparison of wide-character codes performed.
+Otherwise, the results are unspecified.
+.P
+The information for
+\fIwcscasecmp_l\fR()
+and
+\fIwcsncasecmp_l\fR()
+about the case of the characters comes from the locale represented by
+.IR locale .
+.P
+The behavior is undefined if the
+.IR locale
+argument to
+\fIwcscasecmp_l\fR()
+or
+\fIwcsncasecmp_l\fR()
+is the special locale object LC_GLOBAL_LOCALE or is not a valid locale
+object handle.
+.SH "RETURN VALUE"
+Upon completion, the
+\fIwcscasecmp\fR()
+and
+\fIwcscasecmp_l\fR()
+functions shall return an integer greater than, equal to, or less than 0
+if the wide-character string pointed to by
+.IR ws1
+is, ignoring case, greater than, equal to, or less than the
+wide-character string pointed to by
+.IR ws2 ,
+respectively.
+.P
+Upon completion, the
+\fIwcsncasecmp\fR()
+and
+\fIwcsncasecmp_l\fR()
+functions shall return an integer greater than, equal to, or less than 0
+if the possibly null wide-character terminated string pointed to by
+.IR ws1
+is, ignoring case, greater than, equal to, or less than the possibly
+null wide-character terminated string pointed to by
+.IR ws2 ,
+respectively.
+.P
+No return values are reserved to indicate an error.
