Berkeley DB: DB_ENV->log_printf
|
DB_ENV->log_printf
|
 |
#include <db.h>
int
DB_ENV->log_printf(DB_ENV *env, DB_TXN *txnid, const char *fmt, ...);
Description: DB_ENV->log_printf
The DB_ENV->log_printf method appends an informational message to the Berkeley DB
database environment log files.
The DB_ENV->log_printf method allows applications to include information in
the database environment log files, for later review using the
db_printlog utility. This method is intended for debugging and
performance tuning.
The DB_ENV->log_printf method
returns a non-zero error value on failure
and 0 on success.
Parameters
txnid- If the logged message refers to an application-specified transaction,
the txnid parameter is a transaction handle returned from
DB_ENV->txn_begin; otherwise NULL.
fmt- A format string that specifies how subsequent arguments (or arguments
accessed via the variable-length argument facilities of stdarg(3)) are
converted for output. The format string may contain any formatting
directives supported by the underlying C library vsnprintf(3)
function.
Errors
The DB_ENV->log_printf method
may fail and return one of the following non-zero errors:
EINVAL- An
invalid flag value or parameter was specified.
Class
DB_ENV, DB_LOGC, DB_LSN
