3.  Runtime Linker Debugging Aids Debugger Module  Previous   Contents   Next 

At this point, new objects have been loaded:

> *`lml_main::Rt_maps
rtmap*     ADDR       NAME
0xff3b0030 0x00010000 main
0xff3b0434 0xff3a0000 /usr/lib/
0xff3b0734 0xff280000 /usr/lib/
0xff3b0c1c 0xff370000 ./
0xff3b1030 0xff350000 ./

The link-map for shows the handle returned by dlopen(3DL). You can expand this structure using Dl_handle.

> 0xff3b0c1c::Rt_map
Rt_map located at: 0xff3b0c1c
    NAME: ./
    ADDR: 0xff370000   DYN: 0xff3805c8
    NEXT: 0xff3b1030  PREV: 0xff3b0734
     FCT: 0xff3f6080
  PERMIT: 0xff3b0f94 HANDLE: 0xff3b0f38

> 0xff3b0f38::Dl_handle
Dl_handle located at: ff3b0f38
   permit: 0xff3b0f7c
  usercnt:        1 permcnt:        2
  depends: 0xff3b0f44 [0xff3b0fc4, 0xff3b1358]
  parents: 0xff3b0f4c [0x00000000, 0x00000000]

The dependencies of a handle are a list of link-maps that represent the objects of the handle that can satisfy a dlsym(3DL) request:

> 0xff3b0f44::ListRtmap
Listnode   data       next       Rt_map name
0xff3b0fc4 0xff3b0c1c 0xff3b1358 ./
0xff3b1358 0xff3b1030 0x00000000 ./

Note - The above examples provide a basic guide to the debugger module capabilities, but the exact commands, usage, and output may change from release to release. Refer to any usage or help information for the exact capabilities available on your system.
