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.
