.SH NAME
wcsncmp \- compare part of two wide-character strings
.SH SYNOPSIS
.LP
\fB#include <wchar.h>
.br
.sp
int wcsncmp(const wchar_t *\fP\fIws1\fP\fB, const wchar_t *\fP\fIws2\fP\fB,
size_t\fP \fIn\fP\fB);
.br
\fP
.SH DESCRIPTION
.LP
The \fIwcsncmp\fP() function shall compare not more than \fIn\fP wide-character
codes (wide-character codes that follow a null
wide-character code are not compared) from the array pointed to by
\fIws1\fP to the array pointed to by \fIws2\fP.
.LP
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.
.SH RETURN VALUE
.LP
Upon successful completion, \fIwcsncmp\fP() shall return an integer
greater than, equal to, or less than 0, if the possibly
null-terminated array pointed to by \fIws1\fP is greater than, equal
to, or less than the possibly null-terminated array pointed
to by \fIws2\fP, respectively.
.SH ERRORS
.LP
No errors are defined.
