I've used: #define DIOSDUMPDEV _IOW('p',1,unsigned long) /* set the dump device */ #define DIOGDUMPDEV _IOR('p',2,unsigned long) /* get the dump device */ #define DIOSDUMPLEVEL _IOW('p',3,unsigned long) /* set the dump level */ #define DIOGDUMPLEVEL _IOR('p',4,unsigned long) /* get the dump level */ #define DIOSDUMPFLAGS _IOW('p',5,unsigned long) /* set the dump flag parameters */ #define DIOGDUMPFLAGS _IOR('p',6,unsigned long) /* get the dump flag parameters */ #define DIOSDUMPCOMPRESS _IOW('p',7,unsigned long) /* set the dump compress level */ #define DIOGDUMPCOMPRESS _IOR('p',8,unsigned long) /* get the dump compress level */ #define DIOGDINDEX _IOR('p',9,unsigned long) /* get the number of configured device */ But I don't understand what's wrong, does I need to declare something else somewhere else ????
