Inheritance diagram for sbuild::device_lock:


Public Member Functions | |
| device_lock (std::string const &device) | |
| The constructor. | |
| virtual | ~device_lock () |
| The destructor. | |
| virtual void | set_lock (lock::type lock_type, unsigned int timeout) |
| Acquire a lock. | |
| virtual void | unset_lock () |
| Release a lock. | |
Private Attributes | |
| std::string | device |
| The device to lock. | |
Set an advisory lock on a device. The lock is acquired using liblockdev lock_dev(). Note that a lock_type of LOCK_SHARED is equivalent to LOCK_EXCLUSIVE, because this lock type does not support shared locks.

The constructor.
| device | the device to lock (full pathname). |
| device_lock::~device_lock | ( | ) | [virtual] |

| void device_lock::set_lock | ( | lock::type | lock_type, | |
| unsigned int | timeout | |||
| ) | [virtual] |
Acquire a lock.
| lock_type | the type of lock to acquire. | |
| timeout | the time in seconds to wait on the lock. |
Implements sbuild::lock.

This is equivalent to set_lock with a lock_type of LOCK_NONE and a timeout of 0.
Implements sbuild::lock.
std::string sbuild::device_lock::device [private] |
