<h1>Description</h1>
|
|
<p>The DbEnv::lock_id method
|
|
copies a locker ID, which is guaranteed to be unique in the specified lock
|
|
table, into the memory location referenced by <b>idp</b>.
|
|
<p>The DbEnv::lock_id method either returns a non-zero error value or throws an exception that
|
|
encapsulates a non-zero error value on failure, and returns 0 on success.
|
|
<h1>Errors</h1>
|
|
<p>The DbEnv::lock_id method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
|
|
If a catastrophic error has occurred, the DbEnv::lock_id method may fail and either
|
|
return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw an exception encapsulating
|
|
<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
|
|
in the same way.
