函数名称：moyo_read_domain - Read domain policy.*@head: Pointer to "struct tomoyo_io_buffer".* Caller holds tomoyo_read_lock().

函数原型：static void tomoyo_read_domain(struct tomoyo_io_buffer *head)

返回类型：void

参数：

类型参数名称
struct tomoyo_io_buffer *head
1620  如果eof则返回
1623  domain等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(domain, typeof( * domain), list)
1628  当:step恒等于0
1629  如果 Delete flag. 且非print_this_domain_only则继续下一循环
1633  moyo_set_string - Queue string to "struct tomoyo_io_buffer" structure
1634  moyo_set_lf - Put a line feed to "struct tomoyo_io_buffer" structure.*@head: Pointer to "struct tomoyo_io_buffer".* Returns nothing.
1635  moyo_io_printf - printf() to "struct tomoyo_io_buffer" structure.*@head: Pointer to "struct tomoyo_io_buffer".*@fmt: The printf()'s format string, followed by parameters.
1637  以i小于TOMOYO_MAX_DOMAIN_INFO_FLAGS循环如果flags[i]则
1639  moyo_set_string - Queue string to "struct tomoyo_io_buffer" structure
1640  index等于0
1641  step自加
1643  当:step恒等于1
1644  当index小于Group number is an integer between 0 and 255. 循环
1645  i等于index自加
1646  如果非st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则继续下一循环
1648  moyo_io_printf - printf() to "struct tomoyo_io_buffer" structure.*@head: Pointer to "struct tomoyo_io_buffer".*@fmt: The printf()'s format string, followed by parameters.
1649  如果非moyo_flush - Flush queued string to userspace's buffer.*@head: Pointer to "struct tomoyo_io_buffer".* Returns true if all data was flushed, false otherwise.则返回
1652  index等于0
1653  step自加
1654  moyo_set_lf - Put a line feed to "struct tomoyo_io_buffer" structure.*@head: Pointer to "struct tomoyo_io_buffer".* Returns nothing.
1656  当:step恒等于2
1657  如果非moyo_read_domain2 - Read domain policy.*@head: Pointer to "struct tomoyo_io_buffer".*@list: Pointer to "struct list_head".* Caller holds tomoyo_read_lock().* Returns true on success, false otherwise.则返回
1659  step自加
1660  如果非moyo_set_lf - Put a line feed to "struct tomoyo_io_buffer" structure.*@head: Pointer to "struct tomoyo_io_buffer".* Returns nothing.则返回
1663  当:step恒等于3
1664  step等于0
1665  如果print_this_domain_only则转到:done
1669  done :
1670  eof = true
