To produce annotations, start GDB with the --annotate=2 option.
Annotations start with a newline character, two `control-z' characters, and the name of the annotation. If there is no additional information associated with this annotation, the name of the annotation is followed immediately by a newline. If there is additional information, the name of the annotation is followed by a space, the additional information, and a newline. The additional information cannot contain newline characters.
Any output not beginning with a newline and two `control-z' characters denotes literal output from GDB. Currently there is no need for GDB to output a newline followed by two `control-z' characters, but if there was such a need, the annotations could be extended with an `escape' annotation which means those three characters as output.
A simple example of starting up GDB with annotations is:
$ gdb --annotate=2 GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions. There is absolutely no warranty for GDB; type "show warranty" for details. GDB 4.12.3 (sparc-sun-sunos4.1.3), Copyright 1994 Free Software Foundation, Inc. ^Z^Zpre-prompt (gdb) ^Z^Zprompt quit ^Z^Zpost-prompt $
Here `quit' is input to GDB; the rest is output from GDB. The three lines beginning `^Z^Z' (where `^Z' denotes a `control-z' character) are annotations; the rest is output from GDB.
