The VmbChannelSetTransactionQuota function sets the incoming packet quota.

Syntax

FN_VMB_CHANNEL_SET_TRANSACTION_QUOTA FnVmbChannelSetTransactionQuota;

void FnVmbChannelSetTransactionQuota(
  VMBCHANNEL Channel,
  UINT32 Quota
)
{...}

Parameters

Channel

A handle for a channel.

Quota

The maximum outstanding packet quota. This value must be greater than 0.

Return value

None

Remarks

The incoming packet quota can be set to be lower than the current outstanding packet count. In that case, no new packets are removed from the queue until sufficient packets have been completed.

If the queue is currently blocked due to quota, this operation does not restart it. The queue only restarts once a packet is completed.

Important

This function is called through the VMBus Kernel Mode Client Library (KMCL) interface, provided by the Vmbkmcl.sys bus driver. This is a client function accessed from the KMCL_CLIENT_INTERFACE_V1 structure.

For more information, see the Remarks section of the KMCL_CLIENT_INTERFACE_V1.
