Debugging of Crash Dumps

The libcrash library provides debugger owners and others with code that reads crash dumps. This library insulates the debuggers from the details of the crash dump format, allowing them to handle any type of crash dump with equal ease. The main kernel crash dump debuggers, q4 and adb(1), use this library.As mentioned under “Post-Reboot Dump Processing”, it is no longer necessary to save the crash dump from the dump device into the file system before it can be debugged. savecrash(1M) must be run -- it has to create a directory for the dump and an INDEX file, at minimum -- but it can be told not to copy the dump data out of the dump devices.
