I think it should be cleaner to define STRUCT_file_clone_range in linux-user/syscall_types.h with STRUCT() macro, and then to use it: STRUCT(file_clone_range, TYPE_LONGLONG, /* src_fd */ TYPE_ULONGLONG, /* src_offset */ TYPE_ULONGLONG, /* src_length */ TYPE_ULONGLONG) /* dest_offset */ IOCTL(FICLONERANGE, IOC_W, MK_PTR(MK_STRUCT(STRUCT_file_clone_range))) Laurent
