This function provides a way to get a list of all the DLLs (see
dyn.load) that are currently loaded in the R session.
An object of class "DLLInfoList" which is a list
with an element corresponding to each DLL that is currently loaded in the
session. Each element is an object of class "DLLInfo" which
has the following entries.
the abbreviated name.
the fully qualified name of the loaded DLL.
a logical value indicating whether R uses only
the registration information to resolve symbols or whether it
searches the entire symbol table of the DLL.
a reference to the C-level data structure that
provides access to the contents of the DLL.
This is an object of class "DLLHandle".
Note that the class DLLInfo has a method for
$ which can be used to resolve native symbols within that
DLL. Therefore, one must access the R-level elements described
above using [[, e.g.\sspacex[["name"]] or x[["handle"]].
This queries the internal table that manages the DLLs.
