Checking for attached console is one possibility.
AttachConsole(ATTACH_PARENT_CONSOLE)

Remarks
The calling application can call any of the console functions. For 
example, a graphical application can use the console to display 
debugging output.

A process can be attached to one console. If the calling process is 
already attached to a console, AttachConsole fails with ERROR_ACCESS_DENIED.
