$exitonterminationofprocesswithpid |
None |
If set to process ID (pid), when that process terminates, the debugger exits. |
|
1 |
If set to 0 (the default), prints 128-bit floating point numbers normally;if set to a non-zero value, prints 128-bit floating point numbers as 128-bit containsers holding 80-bit floating point numbers. | |
|
1 |
If set to the default (1), the debugger prints binary floating point numbers using the shortest possible decimal number. If set to 0, the debugger prints the decimal number which is the closest representation in the number of decimal digits available of the internal binary number. | |
| $framesearchlimit |
0 |
Defines the maximum number of call frames by which to extend normal language-based identifier lookups. |
| $funcsig |
1 |
Displays function signature at breakpoint. |
| $gdb_compatible_output |
0 |
Makes the IDB's output to be fully compatible with GDB's output. |
| $givedebughints |
1 |
Displays hints on debugger features. |
| $hasmeta |
0 |
Interprets multibyte characters. |
| $hexints |
0 |
Displays integers in hex radix. |
| $highpc |
(internal debugger variable) |
Returns the highest address associated with "function". |
| $historylines |
20 |
Defines the number of commands to show for history. |
| $indent |
1 |
Prints structures with indentation. |
| $lang |

| $lasteventmade |
0 |
Displays the number of last (successful) breakpoint definition. |
| $lc_ctype |
result of |
Defines the current locale information. If set, passes the value through setlocale() and becomes the result. "" is passed as 0L. |
| $listwindow |
20 |
Displays the number of lines to show for list. |
| $main |
"main" |
Displays the name of the first routine in the program. |
| $maxstrlen |
128 |
Defines the largest string to print fully. |
| $memorymatchall |
0 |
When set to non-zero, displays all memory matches in the specified range. Otherwise, only the first memory match is displayed. |
| $octints |
0 |
Displays integers in octal radix. |
| $overloadmenu |
1 |
Prompts for choice of overloaded C++ name. |
| $page |
1 |
Paginates debugger terminal output. |
| $pagewindow |
0 |
Defines the number of lines per output page. The default of 0 causes the debugger to query the terminal for the page size. |
| $parallel_branchingfactor |
8 |
Specifies the factor used to build the n-nary tree and determine the number of aggregators in the tree. |
| $parallel_aggregatordelay |
3000 milliseconds |
Specifies the length of time that aggregators wait before they aggregate and send messages down to the next level when not all the expected messages have been received. |
| $parentprocess |

When the debugger detects a fork, it assigns the parent process ID to $parentprocess. |

Echoes input to log file on playback input. |
| $prompt |
"(idb) " |

Controls the format of register names
during disassembly.
Valid settings are:
|
| $repeatmode |
1 |
Repeats previous command when you press the Enter key. |
| $reportsotrans |
0 |
Report when an event was changed because a shared object was either opened or closed. |
| $showlineonstartup |
0 |
Displays the first executable line in main. |
