A.2.3.9 Configuration Functions

A NIC driver configures itself using information in the Configuration Registry and the configuration functions provided by the NDIS interface library, as Table A.2.12 shows. The Configuration Registry module name the driver uses should not conflict with the module names for other drivers. Keyword names are not restricted since keywords for one module are independent of those for another module.

Table A.2.12 Configuration Functions

Function	Definition
NdisCloseConfiguration	Closes a Configuration Registry database that NdisOpenConfiguration has opened.
NdisImmediateReadPciSlotInformation	Reads a specified number of bytes from the configuration space of a specified PCI device.
NdisImmediateWritePciSlotInformation	Writes a specified number of bytes to the configuration space of a specified PCI device.
NdisOpenConfiguration	Opens the Configuration Registry database for a network interface card.
NdisPciAssignResources	Returns a list of resources used by a specified PCI device.
NdisReadBindingInformation	Reads the Configuration Registry to retrieve the name of a lower-level driver that an intermediate driver treats as a network interface card.
NdisReadConfiguration	Reads the value associated with an individual keyword from the Configuration Registry database for a network interface card.
NdisReadEisaSlotInformation	Reads slot information for an EISA network interface card.
NdisReadMcaPosInformation	Reads data from the POS register on an MCA network interface card.
NdisReadNetworkAddress	Reads the software-configured network address of a network interface card from a Configuration Registry database. Driver writers should use the keyword NetworkAddress for network addresses that are software-configurable.
NdisReadPciSlotInformation	Reads a specified number of bytes from the configuration space of a specified PCI device.
NdisWritePciSlotInformation	Writes a specified number of bytes to the configuration space of a specified PCI device.
