NDIS Upper-Edge Functions (Windows Embedded CE 6.0)

1/6/2010

The following table shows the NDIS Upper-Edge driver functions with a description of the purpose of each.

Programming element	Description
DriverEntry	DriverEntry is a required function that the system calls first in any NDIS driver.
MiniportCancelSendPackets	The MiniportCancelSendPackets function is optional.
MiniportCheckForHang	This function is an optional function that reports the state of the network adapter or monitors the responsiveness of an underlying device driver.
MiniportDisableInterrupt	This function is an optional function, supplied by drivers of network adapters that support dynamic enabling and disabling of interrupts but do not share an IRQ.
MiniportEnableInterrupt	MiniportEnableInterrupt is an optional function, supplied by some drivers of network adapters that support dynamic enabling and disabling of interrupts but do not share an IRQ.
MiniportHalt	MiniportHalt is a required function that de-allocates resources when the network adapter is removed and halts the network adapter.
MiniportHandleInterrupt	This function is a required function if a driver's network adapter generates interrupts.
MiniportInitialize	This function is a required function that sets up a network adapter, or virtual network adapter, for network I/O operations, claims all hardware resources necessary to the network adapter in the registry, and allocates resources the driver needs to carry out network I/O operations.
MiniportISR	This function is a required function if the driver's network adapter generates interrupts.
MiniportQueryInformation	This function is a required function that returns information about the capabilities and status of the driver and/or its network adapter.
MiniportReconfigure	Although the NDIS library currently never calls this function, a MiniportInitialize function can call it as an internal driver function.
MiniportReset	This function is a required function that issues a hardware reset to the network adapter and/or resets the driver's software state.
MiniportReturnPacket	This function is a required function in drivers that indicate receives with NdisMIndicateReceivePacket.
MiniportSend	This function transfers a protocol-supplied packet over the network.
MiniportSendPackets	MiniportSendPackets is a required function if the driver has no MiniportSend, or MiniportWanSend function.
MiniportSetInformation	This function is a required function that allows bound protocol drivers, or NDIS, to request changes in the state information that the miniport maintains for particular object identifiers, such as changes in multicast addresses.
MiniportShutdown	MiniportShutdown is an optional function that restores a NIC to its initial state when the system is shut down, whether by the user or because an unrecoverable system error occurred.
MiniportSynchronizeISR	MiniportSynchronizeISR is a required function for NIC driver functions that run at less than DIRQL and share resources with that driver's MiniportISR or MiniportDisableInterrupt function.
MiniportTimer	MiniportTimer is a required function if a driver's NIC does not generate interrupts.
MiniportTransferData	This function is a required function in network adapter drivers that do not indicate multipacket receives and/or media-specific information with NdisMIndicateReceivePacket and in those that do not support WAN media.
MiniportWanSend	This function is a required function if the driver controls a WAN network adapter.
