Simple Examples of GDB/MI Interaction

This subsection presents several simple examples of interaction using the GDB/MI interface. In these examples, -> means that the following line is passed to GDB/MI as input, while <- means the output received from GDB/MI.

Target Stop

Here's an example of stopping the inferior process:

     -> -stop
     <- (gdb)
     

and later:

     <- *stop,reason="stop",address="0x123",source="a.c:123"
     <- (gdb)
     

Simple CLI Command

Here's an example of a simple CLI command being passed through GDB/MI and on to the CLI.

     -> print 1+2
     <- &"print 1+2\n"
     <- ~"$1 = 3\n"
     <- ^done
     <- (gdb)
     

Command With Side Effects

     -> -symbol-file xyz.exe
     <- *breakpoint,nr="3",address="0x123",source="a.c:123"
     <- (gdb)
     

A Bad Command

Here's what happens if you pass a non-existent command:

     -> -rubbish
     <- ^error,msg="Undefined MI command: rubbish"
     <- (gdb)
