28 function is the wide-character equivalent of the
31 It copies at most \fIn\fP wide characters from the wide-character
32 string pointed to by \fIsrc\fP,
33 including the terminating null wide character (L\(aq\\0\(aq),
34 to the array pointed to by \fIdest\fP.
35 Exactly \fIn\fP wide characters are
36 written at \fIdest\fP.
37 If the length \fIwcslen(src)\fP is smaller than \fIn\fP,
38 the remaining wide characters in the array
39 pointed to by \fIdest\fP are filled
40 with null wide characters.
41 If the length \fIwcslen(src)\fP is greater or equal
42 to \fIn\fP, the string pointed to by \fIdest\fP
43 will not be terminated by a null wide character.
45 The strings may not overlap.
47 The programmer must ensure that there is room for at least \fIn\fP wide
48 characters at \fIdest\fP.
