Detailed Description

Control the debugging of a process.

Debugger functions complete either SYNCHRONOUSLY or ASYNCHRONOUSLY:

• SYNCHRONOUS FUNCTIONS execute the entire action before the function returns.
• ASYNCHRONOUS FUNCTIONS return before the action has executed in its entirety. They simply start the action, but the result of the action will only be available later. For example, run_to() can execute a lot of instructions before terminating. Such functions provide a notification code to indicate the end of their execution (see the 'Notification' keyword in the function documentation). Install a callback using hook_to_notification_point() to be notified when the action is terminated.

DEBUGGER COMMANDS are functions who influence the execution of the debugged process. They are available in 2 forms:

• COMMAND(): (e.g. suspend_process()) In this mode, the command will be directly executed. However, it is forbidden to use asynchronous commands in this mode from a debugger notification handler (see dbg_notification_t).
• request_COMMAND(): (e.g. request_suspend_process()) In this mode, a REQUEST to run the command will be memorized at the end of the REQUEST QUEUE (see below). This is mandatory to use this mode for asynchronous commands from a debugger notification handler (see dbg_notification_t).

The REQUEST QUEUE contains a list of planned debugger commands. These commands will be started only in the following cases:

• the previous command terminated, and no call to suspend_process() or continue_process() occurred in the asynchronous function result notification handler (if any).
• run_requests() was called. Please note that when called from a debugger notification handler the queued requests will only be started after the execution of all notification handlers.

A request which fails to start (by returning 0) will generate a dbg_request_error notification.

Function Documentation

run_requests()

bool idaapi run_requests ( void  )

inline

Execute requests until all requests are processed or an asynchronous function is called.

Type	Synchronous function
Notification	none (synchronous function)

Returns

false if not all requests could be processed (indicates an asynchronous function was started)

Note

If called from a notification handler, the execution of requests will be postponed to the end of the execution of all notification handlers.

get_running_request()

ui_notification_t idaapi get_running_request ( void  )

inline

Get the current running request.

Type	Synchronous function
Notification	none (synchronous function)

Returns

ui_null if no running request

get_running_notification()

dbg_notification_t idaapi get_running_notification ( void  )

inline

Get the notification associated (if any) with the current running request.

Type	Synchronous function
Notification	none (synchronous function)

Returns

dbg_null if no running request

clear_requests_queue()

void idaapi clear_requests_queue ( void  )

inline

Clear the queue of waiting requests.

Type	Synchronous function
Notification	none (synchronous function)

Note

If a request is currently running, this one isn't stopped.
