| mdb(1) is an extensible utility for low-level debugging and editing of the |
| live operating system, operating system crash dumps, user processes, user |
| process core dumps, and object files. mdb provides a completely customizable |
| environment for debugging complex software systems such as an operating system, |
| for programs that are highly optimized, have had their debug information |
| removed, or are themselves low-level debugging tools, and for customer |
| situations where developers can only access post-mortem information. |
| |
| Refer to the white paper "A Modular Debugger for Solaris" for information |
| on the design, features, and goals of MDB. See /shared/sac/PSARC/1999/169 |
| for copies of the paper and related documentation. More information about |
| MDB is available on the internal web at http://mdb.eng/. This directory |
| contains both the source for the MDB debugger, and the supporting debugger |
| modules. Developers are free to modify and enhance these modules to add |
| new dcmds and walkers and to create completely new modules. |
