SvcResult HandleDuplicate(Handle h, HandlePerms perms, Marker marker);

Registers: (h, perms, marker) -> r0 status, r1 new handle

marker is only applied when h is a port owned by the caller's space; a server uses it to tell its callers apart. Any other handle keeps its current marker. HandleDup() is the easier form.

Parameters

Name	Direction	Description
h	in	Handle to duplicate.
perms	in	Permissions for the copy; intersected with those of h.
marker	in	Marker for the copy (own ports only).

Returns

r0 is the status; r1 the new handle on success.

Errors

Error	Condition
ERR_BADHANDLE	h is not a live handle.
ERR_NOMEM	The caller's handle table is full.
