DJ Command
DJ Command
The DJ command displays the contents of a specified jump buffer in register format.
The form of the DJ command is:
32-bit-address
is the RISC address of a jump buffer.
Considerations
•
The DJ command causes a subset of the TNS/R registers to be displayed.
Registers that are not saved in the jump buffer are not displayed.
•
The default numeric base for the DJ command is hexadecimal.
•
A jump buffer is used for saving the context of a process. For more information
about jump buffers and their use, refer to the descriptions of the SETJMP_,
LONGJMP_, SIGSETJMP_, and SIGLONGJMP_ procedures in the Guardian
Procedure Calls Reference Manual.
