.SH NAME
wcsncmp \- compare two fixed-size wide-character strings
.SH SYNOPSIS
function is the wide-character equivalent of the
.BR strncmp (3)
function.
-It compares the wide-character string pointed to by \fIs1\fP and the
-wide-character string pointed to by \fIs2\fP, but at most \fIn\fP wide
+It compares the wide-character string pointed to by
+.I s1
+and the
+wide-character string pointed to by
+.IR s2 ,
+but at most
+.I n
+wide
characters from each string.
In each string, the comparison extends only up
to the first occurrence of a null wide character (L\(aq\\0\(aq), if any.
-.SH "RETURN VALUE"
+.SH RETURN VALUE
The
.BR wcsncmp ()
function returns zero if the wide-character strings at
-\fIs1\fP and \fIs2\fP, truncated to at most length \fIn\fP, are equal.
+.I s1
+and
+.IR s2 ,
+truncated to at most length
+.IR n ,
+are equal.
It returns an integer greater than zero if at the first differing position
-\fIi\fP (\fIi\fP < \fIn\fP),
-the corresponding wide-character \fIs1[i]\fP is
-greater than \fIs2[i]\fP.
+.I i
+.RI ( i
+<
+.IR n ),
+the corresponding wide-character
+.I s1[i]
+is
+greater than
+.IR s2[i] .
It returns an integer less than zero if at the first
-differing position \fIi\fP (\fIi\fP < \fIn\fP), the corresponding
-wide-character \fIs1[i]\fP is less than \fIs2[i]\fP.
