Get DLLs Loaded in Current Session (original) (raw)
| getLoadedDLLs {base} | R Documentation |
|---|
Description
This function provides a way to get a list of all the DLLs (see[dyn.load](../../base/help/dyn.load.html)) that are currently loaded in the R session.
Usage
getLoadedDLLs()
Details
This queries the internal table that manages the DLLs.
Value
An object of class "DLLInfoList" which is a [list](../../base/help/list.html)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.
| name | the abbreviated name. |
|---|---|
| path | the fully qualified name of the loaded DLL. |
| dynamicLookup | 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. |
| handle | 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. x[["name"]] or x[["handle"]].
Note
We are starting to use the handle elements in the DLL object to resolve symbols more directly in R.
