+.SH NAME
+wcslen, wcsnlen
+\(em get length of a fixed-sized wide-character string
+.SH SYNOPSIS
+.LP
+.nf
+#include <wchar.h>
+.P
+size_t wcslen(const wchar_t *\fIws\fP);
+size_t wcsnlen(const wchar_t *\fIws\fP, size_t \fImaxlen\fP);
+.fi
+.SH DESCRIPTION
+For
+\fIwcslen\fR():
+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\(hy2017 defers to the ISO\ C standard.
+.P
+The
+\fIwcslen\fR()
+function shall compute the number of wide-character codes in the
+wide-character string to which
+.IR ws
+points, not including the terminating null wide-character code.
+.P
+The
+\fIwcsnlen\fR()
+function shall compute the smaller of the number of wide characters in
+the array to which
+.IR ws
+points, not including any terminating null wide-character code, and the
+value of
+.IR maxlen .
+The
+\fIwcsnlen\fR()
+function shall never examine more than the first
+.IR maxlen
+characters of the wide-character array pointed to by
+.IR ws .
+.SH "RETURN VALUE"
+The
+\fIwcslen\fR()
+function shall return the length of
+.IR ws .
+.P
+The
+\fIwcsnlen\fR()
+function shall return the number of wide characters preceding the
+first null wide-character code in the array to which
+.IR ws
+points, if
+.IR ws
+contains a null wide-character code within the first
+.IR maxlen
+wide characters; otherwise, it shall return
+.IR maxlen .
+.P
+No return values are reserved to indicate an error.
+.SH ERRORS
+No errors are defined.
