Querying the Event Log

The following code sample displays the number of event records currently in the Application event log and the System event log.

/* Open the System log. */

h = OpenEventLog(NULL, /* uses local computer */

"System"); /* source name */

if (h == NULL)

ErrorExit("could not open System event log");

/* Get the number of records in the System event log. */

if (!GetNumberOfEventLogRecords(h, &cRecords))

ErrorExit

("could not get number of records");

printf("There are %d records in the System event log.\n", cRecords);

CloseEventLog(h);

/* Open the Application log. */

h = OpenEventLog(NULL, /* uses local computer */

"Application"); /* source name */

if (h == NULL)

ErrorExit("could not open Application event log");

/* Get the number of records in the Application event log. */

if (!GetNumberOfEventLogRecords(h, &cRecords))

ErrorExit("could not get number of records");

printf("There are %d records in the Application event log.\n",

cRecords);

CloseEventLog(h);
