函数原型：int kdb_putword(unsigned long addr, unsigned long word, size_t size)

返回类型：int

参数：

类型参数名称
unsigned longaddr
unsigned longword
size_tsize
510  当:size恒等于1
511  w1等于word
512  diag等于kdb_putarea(addr, w1)
513  退出
514  当:size恒等于2
515  w2等于word
516  diag等于kdb_putarea(addr, w2)
517  退出
518  当:size恒等于4
519  w4等于word
520  diag等于kdb_putarea(addr, w4)
521  退出
522  当:size恒等于8
523  如果size小于等于word的长度则
524  w8等于word
525  diag等于kdb_putarea(addr, w8)
526  退出
529  默认
530  diag等于KDB_BADWIDTH
531  kdb_printf("kdb_putword: bad width %ld\n", (long)size)
533  返回:diag
