gdb: GDB/MI Result Records
27.5.1 GDB/MI Result Records
----------------------------
In addition to a number of out-of-band notifications, the response to a
GDB/MI command includes one of the following result indications:
'"^done" [ "," RESULTS ]'
The synchronous operation was successful, 'RESULTS' are the return
values.
'"^running"'
This result record is equivalent to '^done'. Historically, it was
output instead of '^done' if the command has resumed the target.
This behaviour is maintained for backward compatibility, but all
frontends should treat '^done' and '^running' identically and rely
on the '*running' output record to determine which threads are
resumed.
'"^connected"'
GDB has connected to a remote target.
'"^error" "," "msg=" C-STRING [ "," "code=" C-STRING ]'
The operation failed. The 'msg=C-STRING' variable contains the
corresponding error message.
If present, the 'code=C-STRING' variable provides an error code on
which consumers can rely on to detect the corresponding error
condition. At present, only one error code is defined:
'"undefined-command"'
Indicates that the command causing the error does not exist.
'"^exit"'
GDB has terminated.
