#include <db_cxx.h>int DbLogc::get(DbLsn *lsn, Dbt *data, u_int32_t flags);
The DbLogc::logc_get method retrieve records from the log according to the lsn and flags arguments.
The data field of the data structure is set to the record retrieved, and the size field indicates the number of bytes in the record. See Dbt for a description of other fields in the data structure. The DB_DBT_MALLOC, DB_DBT_REALLOC and DB_DBT_USERMEM flags may be specified for any Dbt used for data retrieval.
The flags value must be set to one of the following values:
If the log is empty, the DbLogc::logc_get method will return DB_NOTFOUND.
If the log is empty, the DbLogc::logc_get method will return DB_NOTFOUND.
If the log is empty, the DbLogc::logc_get method will return DB_NOTFOUND.
If the pointer has not been initialized via DB_FIRST, DB_LAST, DB_SET, DB_NEXT, or DB_PREV, DbLogc::logc_get will return the first (last) record in the log. If the last (first) log record has already been returned or the log is empty, the DbLogc::logc_get method will return DB_NOTFOUND.
If the log was opened with the DB_THREAD flag set, calls to DbLogc::logc_get with the DB_NEXT (DB_PREV) flag set will return EINVAL.
If the log pointer has not been initialized via DB_FIRST, DB_LAST, DB_SET, DB_NEXT, or DB_PREV, or if the log was opened with the DB_THREAD flag set, DbLogc::logc_get will return EINVAL.
Otherwise, the DbLogc::logc_get 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.
The DbLogc::logc_get method may fail and throw an exception or return a non-zero error for the following conditions:
The DB_CURRENT flag was set and the log pointer had not yet been initialized.
The DB_SET flag was set and the specified log sequence number does not exist.
The DbLogc::logc_get 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 DbLogc::logc_get method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
