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-outputcontains on-going status information about the progress of a slow operation. It can be discarded. All status output is prefixed by '+'.

•exec-async-outputcontains asynchronous state change on the target (stopped, started, disappeared). All async output is prefixed by '*'.

•notify-async-outputcontains supplementary information that the client should handle (for example, a new breakpoint information). All notify output is prefixed by '='.

•console-stream-outputis 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-outputis the output produced by the target program. All the target output is prefixed by '@'.

•log-stream-outputis 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.
