19.3.2 GDB/MI Stream Records

GDB internally maintains a number of output streams: the console, the target, and the log. The output intended for each of these streams is funneled through the GDB/MI interface using stream records.

Each stream record begins with a unique prefix character which identifies its stream (see section GDB/MI Output Syntax). In addition to the prefix, each stream record contains a string-output. This is either raw text (with an implicit new line) or a quoted C string (which does not contain an implicit newline).

"~" string-output

The console output stream contains text that should be displayed in the CLI console window. It contains the textual responses to CLI commands.

"@" string-output

The target output stream contains any textual output from the running target.

"&" string-output

The LOG stream contains debugging messages being produced by GDB's internals.
