Hello everyone, I'm trying to add a new ioctrl to the syscons driver and have defined it as _IOWR('c', 106, shipout_t) right after CONS_SCRSHOT in consio.h. My question is how do I know that the group ('c') and number (106) I'm using are not in conflict with other ioctrls ? Is there a file where all the ioctrls are listed ? Thanx a lot in advance. Mike
