LogCloseEventNotification
LogCloseEventNotification closes event-notification requests.
Syntax
LogCloseEventNotification(service, pCloseEventNotification);
Parameters
- service (ULONG) - input
- The class of Logging Service:
- Error logging
- All other values are reserved for future use.
- pCloseEventNotification (PVOID) - in/out
- A pointer to the LogCloseEventNotification parameter packet.
- For Error Logging, this is a pointer to a LCENREQUEST structure.
Returns
- rc (APIRET) - returns
- Return code.
LogCloseEventNotification returns the following values:
- 0 No error
- 523 Error lf invalid service
- 1703 Invalid data pointer
- 1702 Invalid LF packet revision number
- 1706 RAS invalid parm packet ptr
- 1758 RAS invalid log notify id
- 1761 RAS invalid packet size
- 2502 RAS internal memory failure
- 2503 RAS notify entry not found
Remarks
The library LFAPI.LIB must be linked with object files that use LogCloseEventNotification
Example Code
#define INCL_LOGGING #include <os2.h> #include <lfdef.h> ULONG service; PVOID pCloseEventNotification; APIRET rc; rc = LogCloseEventNotification(service, pCloseEventNotification);
The following example closes an event-notification mechanism that is connected to the Error Logging service.
#define INCL_LOGGING
#include <unidef.h>
#include <os2.h>
#include <stdio.h>
#include <lfdef.h>
{
APIRET rc; /* return code */
ULONG service;
LCENREQUEST close_event_packet;
HLOGNOTIFY log_notify;
service = ERROR_LOGGING_SERVICE;
/* Construct the LogChangeEventFilter parameter packet */
close_event_packet.packet_size = sizeof(LCENREQUEST);
close_event_packet.packet_revision_number = LF_UNI_API;
close_event_packet.LogNotify = log_notify;
rc = LogCloseEventNotification(service, /* service */
&close_event_packet) /* parameter packet */
if (rc |= 0)
{
printf("LogCloseEventNotification error: return code = %d",rc);
return;
}
