This packet is not probed by default; the remote stub must request it,

+If the remote stub indicates it supports the augmented form of this

+contain a semicolon-separated list of @samp{@var{name}=@var{value}}
+arguments. The currently supported arguments are:

+A hexadecimal number specifying the address of the @samp{struct

+then the first @samp{struct link_map} in the library list will be

+@item prev=@var{address}
+A hexadecimal number specifying the address of the @samp{struct

+specified by the @samp{start} argument. If unset or zero then
