  • Article

The RtmGetEnumNextHops function retrieves the next set of next hops in the specified enumeration.

Syntax

DWORD RtmGetEnumNextHops(
  [in]      RTM_ENTITY_HANDLE   RtmRegHandle,
  [in]      RTM_ENUM_HANDLE     EnumHandle,
  [in, out] PUINT               NumNextHops,
  [out]     PRTM_NEXTHOP_HANDLE NextHopHandles
);

Parameters

[in] RtmRegHandle

Handle to the client obtained from a previous call to RtmRegisterEntity.

[in] EnumHandle

Handle to the next-hop enumeration.

[in, out] NumNextHops

On input, NumNextHops is a pointer to a UINT value specifying the maximum number of next hops that can be received by NextHopHandles.

On output, NumNextHops receives the actual number of next hops received by NextHopHandles.

[out] NextHopHandles

On input, NextHopHandles pointers to an RTM_NEXTHOP_INFO structure.

On output, NextHopHandles receives an array of handles to next hops.

Return value

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is one of the following error codes.

Value Meaning
ERROR_INVALID_PARAMETER
 The value pointed to by NumRoutes is larger than the maximum number of routes a client is allowed to retrieve with one call. Check RTM_REGN_PROFILE for the maximum number of next hops that the client is allowed to retrieve with one call.
ERROR_NO_MORE_ITEMS
 There are no more next hops to enumerate.
 
 

Remarks

When the next hops are no longer required, release them by calling RtmReleaseNextHops.
