.SH DESCRIPTION
|
|
.LP
|
|
The \fImemmove\fP() function shall copy \fIn\fP bytes from the object
|
|
pointed to by \fIs2\fP into the object pointed to by
|
|
\fIs1\fP. Copying takes place as if the \fIn\fP bytes from the object
|
|
pointed to by \fIs2\fP are first copied into a temporary
|
|
array of \fIn\fP bytes that does not overlap the objects pointed to
|
|
by \fIs1\fP and \fIs2\fP, and then the \fIn\fP bytes from
|
|
the temporary array are copied into the object pointed to by \fIs1\fP.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
The \fImemmove\fP() function shall return \fIs1\fP; no return value
