Function name : GetEventLogInformation

Group: Event Logging - Library: advapi32

Retrieves information about the specified event log.

Code examples:

Reading entries from Event logs

Declaration:

BOOL GetEventLogInformation(
  HANDLE hEventLog,
  DWORD dwInfoLevel,
  LPVOID lpBuffer,
  DWORD cbBufSize,
  LPDWORD pcbBytesNeeded
);

FoxPro declaration:

DECLARE INTEGER GetEventLogInformation IN advapi32;
	INTEGER hEventLog,;
	LONG dwInfoLevel,;
	LONG @lpBuffer,;
	LONG cbBufSize,;
	LONG @pcbBytesNeeded

Parameters:

hEventLog [in] A handle to the event log. This handle is returned by the OpenEventLog or RegisterEventSource function.

dwInfoLevel [in] The level of event log information to be returned. Use EVENTLOG_FULL_INFO (0) to find out if the specified log is full.

lpBuffer [out] A pointer to a buffer for the event log information. The format of this data depends on the value of the dwInfoLevel parameter.

cbBufSize [in] The size of the buffer, in bytes.

pcbBytesNeeded [out] A pointer to a variable that receives the number of bytes required for the requested information, regardless of whether the function succeeds. This parameter cannot be NULL.

Return value:

If the function succeeds, the return value is nonzero.

Comments:

At this point, the EVENTLOG_FULL_INFORMATION contains only one member, which indicates whether the log is full.
