SnmpExtensionInitEx

The Microsoft SNMP service calls the SnmpExtensionInitEx function to identify any additional management information base (MIB) subtrees the SNMP extension agent supports. This function is an element of the SNMP Extension Agent API.

BOOL SnmpExtensionInitEx(
  AsnObjectIdentifier *pNextSupportedRegion  // next MIB subtree
);

Parameters

pNextSupportedRegion

[out] Pointer to an AsnObjectIdentifier structure to receive the next MIB subtree that the extension agent supports.

Return Values

If the pNextSupportedRegion parameter has been initialized with an additional MIB subtree, the return value is TRUE.

If there are no more MIB subtrees to register, the return value is FALSE.

Remarks

The SNMP service repeatedly calls the SnmpExtensionInitEx function entry point so the extension agent can register support for additional MIB subtrees.

The SNMP service makes a copy of the AsnObjectIdentifier structure the extension agent returns in the pNextSupportedRegion parameter. The extension agent must allocate and deallocate the resources associated with the original structure. It can do this when the SNMP service calls the SnmpExtensionClose function.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Snmp.h.
