Under Linux it's possible to return values through the ioctl system
call directly (i.e. not a reference argument, but a direct return value). So far I have only seen this with binaries that talk to their own device modules, using non-standard ioctl calls. Hence, allow for a pass-through ioctl call using PTIOCLINUX to return EJUSTRETURN, signalling that the return value is in the 'data' field of the structure, which can then be put in 'retval'.
