paths |
Character vector of paths of shared libraries to look up. They must be absolute paths. They don't need to exist. Forward slashes are converted to backward slashes on Windows, and the output will always have backward slashes in the paths. |

This function currently only works on Windows.
On Windows, a 32 bit R process can only list other 32 bit processes. Similarly, a 64 bit R process can only list other 64 bit processes. This is a limitation of the Windows API.
Even though Windows file systems are (almost always) case
insensitive, the matching of paths, user and also filter
are case sensitive. This might change in the future.
This function can be very slow on Windows, because it needs to
enumerate all shared libraries of all processes in the system,
unless the filter argument is set. Make sure you set filter
if you can.
If you want to look up multiple shared libraries, list all of them
in paths, instead of calling ps_shared_lib_users for each
individually.
If you are after libraries loaded by R processes, you might want to
set filter to c("Rgui.exe", "Rterm.exe", "rsession.exe") The
last one is for RStudio.
A data frame (tibble) with columns:
dll: the file name of the dll file, without the path,
path: path to the shared library,
pid: process ID of the process,
name: name of the process,
username: username of process owner,
ps_handle: ps_handle object, that can be used to further
query and manipulate the process.
Other shared library tools:
ps_shared_libs()
dlls <- vapply(getLoadedDLLs(), "[[", character(1), "path")
psdll <- dlls[["ps"]][[1]]
r_procs <- c("Rgui.exe", "Rterm.exe", "rsession.exe")
ps_shared_lib_users(psdll, filter = r_procs)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
