The ioctl numeric values for SIOCSPGRP are platform-dependent and are determined by following files in Linux kernel source tree: arch/ia64/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902 arch/mips/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t) arch/parisc/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902 arch/sh/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t) arch/xtensa/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t) arch/alpha/include/uapi/asm/sockios.h:#define SIOCSPGRP _IOW('s', 8, pid_t) arch/sparc/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902 include/uapi/asm-generic/sockios.h:#define SIOCSPGRP 0x8902 Hence the different definition for alpha, mips, sh4, and xtensa.
