27.12 GDB/MI Ada Tasking Commands

The -ada-task-info Command

Synopsis

 -ada-task-info [ task-id ]

Reports information about either a specific Ada task, if the task-id parameter is present, or about all Ada tasks.

GDB Command

The ‘info tasks’ command prints the same information about all Ada tasks (see Ada Tasks).

Result

The result is a table of Ada tasks. The following columns are defined for each Ada task:

current

This field exists only for the current thread. It has the value ‘*’.

id

The identifier that GDB uses to refer to the Ada task.

task-id

The identifier that the target uses to refer to the Ada task.

thread-id

The identifier of the thread corresponding to the Ada task.

This field should always exist, as Ada tasks are always implemented on top of a thread. But if GDB cannot find this corresponding thread for any reason, the field is omitted.

parent-id

This field exists only when the task was created by another task. In this case, it provides the ID of the parent task.

priority

The base priority of the task.

state

The current state of the task. For a detailed description of the possible states, see Ada Tasks.

name

The name of the task.
