0:000> !sos.help gctonative 
gctonative:
  Finds GC objects which point to the given native memory ranges.

Usage:
  >!sos gctonative [options] [<memorytypes>...]

Arguments:
  <memorytypes>    The types of memory to search the GC heap for.

Options:
  -a, --all    Show the complete list of objects and not just a summary.

-------------------------------------------------------------------------------
gctonative searches the GC heap for pointers to native memory.  This is used
to help locate regions of native memory that are referenced (or possibly held
alive) by objects on the GC heap.

usage: gctonative [--all] MADDRESS_TYPE_LIST

Note: The MADDRESS_TYPE_LIST must be a memory type as printed by maddress.

If --all is set, a full list of every pointer from the GC heap to the
specified memory will be displayed instead of just a summary table.

Sample Output:

    0:000> gctonative PAGE_READWRITE
    Walking GC heap to find pointers...
    Resolving object names...
