SBTarget supports module, breakpoint, and watchpoint iterations. For example, ::

produces: ::

    (x86_64) /usr/lib/system/libmathCommon.A.dylib
    (x86_64) /usr/lib/libSystem.B.dylib(__commpage)

and, ::

    for b in target.breakpoint_iter():
        print b

produces: ::

    SBBreakpoint: id = 1, file ='main.cpp', line = 66, locations = 1
    SBBreakpoint: id = 2, file ='main.cpp', line = 85, locations = 1

and, ::

    for wp_loc in target.watchpoint_iter():
        print wp_loc

produces: ::

    Launch a new process.

    Launch a new process by spawning a new process using the
    target object's executable module's file as the file to launch.
    Arguments are given in argv, and the environment variables
    are in envp. Standard input and output files can be
    optionally re-directed to stdin_path, stdout_path, and
    stderr_path.

    @param[in] listener
        An optional listener that will receive all process events.
        If listener is valid then listener will listen to all
        process events. If not valid, then this target's debugger
        (SBTarget::GetDebugger()) will listen to all process events.

    @param[in] argv
        The argument array.

    @param[in] envp
        The environment array.

    @param[in] launch_flags
        Flags to modify the launch (@see lldb::LaunchFlags)

    @param[in] stdin_path
        The path to use when re-directing the STDIN of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] stdout_path
        The path to use when re-directing the STDOUT of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] stderr_path
        The path to use when re-directing the STDERR of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] working_directory
        The working directory to have the child process run in

    @param[in] launch_flags
        Some launch options specified by logical OR'ing
        lldb::LaunchFlags enumeration values together.

    @param[in] stop_at_entry
        If false do not stop the inferior at the entry point.

    @param[out]
        An error object. Contains the reason if there is some failure.

    @return
         A process object for the newly created process.

    For example,

        process = target.Launch(self.dbg.GetListener(), None, None,

                                None, 0, False, error)

    launches a new process by passing nothing for both the args and the envs
    and redirect the standard output of the inferior to the /tmp/stdout.txt
    file. It does not specify a working directory so that the debug server
    will use its idea of what the current working directory is for the
    inferior. Also, we ask the debugger not to stop the inferior at the
    entry point. If no breakpoint is specified for the inferior, it should
    run to completion if no user interaction is required."
