This is one of the few situations in the chapter where you need to send a number of pieces of informa-
tion back to IronPython. The 
ConsoleData
structure contains an entry of each piece of information 
that the 
GetConsoleInfo()
provides. An IronPython application can set the output of the call to a 
variable and then use the variable content to determine precisely how the console is configured.
The 
GetConsoleInfo()
method is a little more complicated than the other calls in the extension. 
This method relies on the 
GetConsoleMode()
function to obtain console information. However, 
notice that the method calls the 
GetConsoleMode()
function twice, once with the input handle and 
again with the output handle. This method demonstrates how the use of the wrong handle could 
cause problems because the output from the 
GetConsoleMode()
function differs with the handle 
you provide as input.
The return value from the 
GetConsoleMode()
function is a series of flags. Notice how the code uses 
if
statements to determine whether each flag is set. When a flag is set, the feature is enabled and 
the code sets that value in the 
ConsoleData
data structure, 
Output
, to 
true
. The method ends by 
returning the fully completed 
ConsoleData
data structure to the caller.
