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
- 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.
- 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:
- Indicates that the command causing the error does not exist.
- gdb has terminated.
