.SH NAME
|
|
wcsncpy \- copy a fixed-size string of wide characters
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <wchar.h>
|
|
.PP
|
|
.BI "wchar_t *wcsncpy(wchar_t *" dest ", const wchar_t *" src ", size_t " n );

|
.SH DESCRIPTION
|
|
The
|
|
.BR wcsncpy ()
|
|
function is the wide-character equivalent of the
|
|
.BR strncpy (3)
|
|
function.
|
|
It copies at most
|
|
.I n
|
|
wide characters from the wide-character
|
|
string pointed to by
|
|
.IR src ,
|
|
including the terminating null wide character (L\(aq\\0\(aq),
|
|
to the array pointed to by
|
|
.IR dest .
|
|
Exactly
|
|
.I n
|
|
wide characters are
|
|
written at
|
|
.IR dest .
|
|
If the length \fIwcslen(src)\fP is smaller than
|
|
.IR n ,
|
|
the remaining wide characters in the array
|
|
pointed to by
|
|
.I dest
|
|
are filled
|
|
with null wide characters.
|
|
If the length \fIwcslen(src)\fP is greater than or equal
|
|
to
|
|
.IR n ,
|
|
the string pointed to by
|
|
.I dest
|
|
will not be terminated by a null wide character.
|
|
.PP
|
|
The strings may not overlap.
|
|
.PP
|
|
The programmer must ensure that there is room for at least
|
|
.I n
|
|
wide
|
|
characters at
|
|
.IR dest .
|
|
.SH RETURN VALUE
|
|
.BR wcsncpy ()
|
|
returns
|
|
.IR dest .
