Syntax qed::get_return_value [-h | -help] [-long_help] [-return_token <return_token> ] [-timeout <timeout> ] <object>
Arguments -h | -help Short help
-long_help Long help with examples and possible return values
-return_token <return_token> Token returned by a previous asynchronous run invocation
-timeout <timeout> Optional timeout for waiting for a return value in ms (default = 0 = no timeout)
<object> Identifier associated with the object, must be unique
Description 
Returns data from a command that was run without blocking (using
the "-async" option). You must specify the token returned from
another command such as "qed::launch_connection" or "qed::run_command".

Tokens are not interchangeable between objects. The "qed::get_return_value"
command returns a Tcl error if the given token was not issued by the
given object. The "qed::get_return_value" command blocks until the return
value
Example Usage 
    qed::create_object -type project project_A -qpf_path /file/path/to/project.qpf
    qed::launch_connection project_A
    set tok [qed::run_command project_A -cmd "after 1000; expr {100 * 100}"]

    # Waits for ~1 second and returns 10000
    qed::get_return_value project_A -return_token $tok
