The Test Flag
The "test" (MCI_TEST) flag queries the device to determine if it can execute
the command. The device returns an error if it cannot execute the command. It
returns no error if it can handle the command. When you specify this flag, MCI
returns control to the application without executing the command.
This flag is supported by digital-video and VCR devices for all commands
except open (MCI_OPEN) and close (MCI_CLOSE).
