.SH DESCRIPTION
|
|
The
|
|
.BR wcpcpy ()
|
|
function is the wide-character equivalent of the
|
|
.BR stpcpy (3)
|
|
function.
|
|
It copies the wide-character string pointed to by \fIsrc\fP,
|
|
including the terminating null wide character (L\(aq\\0\(aq),
|
|
to the array pointed to by
|
|
\fIdest\fP.
|
|
.PP
|
|
The strings may not overlap.
|
|
.PP
|
|
The programmer must ensure that there
|
|
is room for at least \fIwcslen(src)+1\fP
|
|
wide characters at \fIdest\fP.
|
|
.SH "RETURN VALUE"
|
|
.BR wcpcpy ()
|
|
returns a pointer to the end of the wide-character string
|
|
\fIdest\fP, that is, a pointer to the terminating null wide character.
