|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
|
|
|
|
If <i>type</i> is 0, the offset is set to <i>n</i> bytes.<br>
|
|
If <i>type</i> is 1, the pointer is set to its current location plus
|
|
<i>n</i>.<br>
|
|
If <i>type</i> is 2, the pointer is set to the size of the file plus
|
|
<i>n</i>.
