PRB: SnmpMgrGetTrap() Fails

ID: Q130564

The information in this article applies to:

Microsoft Win32 Software Development Kit (SDK) for Windows NT version 3.5

SYMPTOMS

If an SNMP manager application calls SnmpMgrGetTrap() to receive traps and there are traps available, it returns FALSE. If the application calls GetLastError(), the error code returned is 42 (SNMP_MGMTAPI_TRAP_ERRORS).

RESOLUTION

The SNMP Manager API SnmpMgrGetTrapListen() must be called before calling SnmpMgrGetTrap(). The event handle returned by SnmpMgrGetTrapListen() can then be ignored to poll for traps.

STATUS

This behavior is by design.
