kStatus kLock_EnterEx | ( | kLock | lock,
|  | k64u | timeout
| ) |  |

Blocks until exclusive ownership of the lock is acquired or the timeout interval has elapsed.

kLock ownership is recursive; the same thread can acquire the lock multiple times without blocking. The lock will be relinquished when the number of calls to kLock_Exit balances the number of successful calls to kLockEnter/kLockEnterEx.

kERROR_TIMEOUT is returned if the timeout elapses before the lock can be acquired.

A debug assertion may be raised if a finite timeout is specified and the lock does not support timeouts.

Parameters

  lock | Lock object.
  timeout | Timeout in microseconds.

Returns
  Operation status.
