token

any sequence of digits.

Notes:
•

All output sequences end in a single line containing a period.

•

The token is from the corresponding request. If an execution command is
interrupted by the '-exec-interrupt' command, the token associated with the
'*stopped' message is the one of the original execution command, not the one of
the interrupt command.

•

status-async-output

contains on-going status information about the progress

of a slow operation. It can be discarded. All status output is prefixed by '+'.

•

exec-async-output

contains asynchronous state change on the target (stopped,

started, disappeared). All async output is prefixed by '*'.

•

notify-async-output

contains supplementary information that the client

should handle (for example, a new breakpoint information). All notify output is
prefixed by '='.

•

console-stream-output

is output that should be displayed as is in the console.

It is the textual response to a CLI command. All the console output is prefixed by
'~'.

•

target-stream-output

is the output produced by the target program. All the

target output is prefixed by '@'.

•

log-stream-output

is output text coming from GDB's internals, for instance

messages that should be displayed as part of an error log. All the log output is
prefixed by '&'.

•

New GDB/MI commands should only output lists containing values.

See

“GDB/MI stream records” (page 311)

, for more details about the various output

records.
