wcsncpy \- copy part of a wide-character string
|

.SH SYNOPSIS

\fB#include <wchar.h>

wchar_t *wcsncpy(wchar_t *restrict\fP \fIws1\fP\fB, const wchar_t

|
.SH DESCRIPTION
|
|
.LP
|
|
The \fIwcsncpy\fP() function shall copy not more than \fIn\fP wide-character
|
|
codes (wide-character codes that follow a null
|
|
wide-character code are not copied) from the array pointed to by \fIws2\fP
|
|
to the array pointed to by \fIws1\fP. If copying takes
|
|
place between objects that overlap, the behavior is undefined.
|
|
.LP
|
|
If the array pointed to by \fIws2\fP is a wide-character string that
|
|
is shorter than \fIn\fP wide-character codes, null
|
|
wide-character codes shall be appended to the copy in the array pointed
|
|
to by \fIws1\fP, until \fIn\fP wide-character codes in
|
|
all are written.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
The \fIwcsncpy\fP() function shall return \fIws1\fP; no return value
|
|
is reserved to indicate an error.
|
|
.SH ERRORS
|
|
.LP
|
|
No errors are defined.
|
|
.LP
|
|
\fIThe following sections are informative.\fP
|
|
.SH EXAMPLES
|
|
.LP
|
|
None.
|
|
.SH APPLICATION USAGE
|
|
.LP
|
|
If there is no null wide-character code in the first \fIn\fP wide-character
|
|
codes of the array pointed to by \fIws2\fP, the
|
|
result is not null-terminated.
|
|
.SH RATIONALE
