Rtnl2GetPhysicalRxQueueConfig

Rtnl2GetPhysicalRxQueueConfig gets the configuration of a Physical Receive Queue.

Syntax

Copy 
BOOL Rtnl2GetPhysicalRxQueueConfig(
  [in]    RTNL2_HINTERFACE Interface,
  [in]    ULONG PhysicalQueueIndex,
  [out]   RTNL2_PHYSICAL_RX_QUEUE_CONFIG *pConfig,
  [in]    ULONG ConfigStructSize
);

Parameters

[in] Interface

A handle to the interface.

[in] PhysicalQueueIndex

The index of the Physical Receive Queue.

[out] pConfig

A structure that contains all the current settings of the Physical Receive Queue.

[in] ConfigStructSize

The size of the RTNL2_PHYSICAL_RX_QUEUE_CONFIG structure allocated by the caller.

Return Value

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. Call GetLastError to obtain an error code.

Possible error codes:

Error code Meaning

ERROR_NOT_READY

The calling process has not called Rtnl2Init.

ERROR_INVALID_PARAMETER

One of the following conditions occurred:

  • The supplied interface handle is invalid.
  • PhysicalQueueIndex is greater or equal to the total number of Physical Receive Queues.
  • pConfig is NULL while ConfigStructSize is a non-zero value.

RTNL2_ERROR_NO_MORE_COMMUNICATION

Unable to communicate with the NL2 process. This might be because the NL2 process is not running anymore, or because an application process thread was terminated during a previous call to an NL2 API function.

Remarks

The caller MUST set ConfigStructSize to sizeof(RTNL2_PHYSICAL_RX_QUEUE_CONFIG) to ensure backward and forward compatibility.

The returned config structure reflects the set of parameters the NL2 uses at startup.
