This function writes a caller-supplied value for a specified entry into the registry.
VOID NdisWriteConfiguration( OUT PNDIS_STATUS Status , IN NDIS_HANDLE WrapperConfigurationContext , IN PNDIS_STRING Keyword , IN PNDIS_CONFIGURATION_PARAMETER * ParameterValue );
Parameters
- Status
- Pointer to a caller-supplied variable in which this function
returns the status of the call as one of the following:
Value Description NDIS_STATUS_SUCCESS The supplied value at ParameterValuewas written into the registry. If this is a new entry, the name at Keywordwas also written into the registry. NDIS_STATUS_NOT_SUPPORTED The supplied ParameterTypeis invalid. NDIS_STATUS_RESOURCES NDIS could not allocate resources, usually enough memory, to transfer the requested information to the registry. NDIS_STATUS_FAILURE The requested information could not be written. - WrapperConfigurationContext
- Specifies the handle returned by the NdisOpenConfigurationor the NdisOpenProtocolConfigurationfunction.
- Keyword
- Pointer to a caller-supplied counted string, in the system-default character set, specifying the name of an entry for which to write the value.
- ParameterValue
- Points to a caller-supplied variable set to the address of a
filled-in
NDIS_CONFIGURATION_PARAMETERstructure.
Remarks
If an entry of the same name as at Keywordalready exists under the opened registry key, this function replaces its current value with the caller-supplied value. Otherwise, this function adds a new value entry with the specified name and supplied value to the registry.
This function buffers and copies the caller-supplied string at Keywordand the caller-supplied data specified at ParameterValue. This memory is freed when the driver releases the ConfigurationHandlewith the NdisCloseConfigurationfunction. The caller of this function is responsible for releasing the buffered string at Keywordand the memory allocated for the NDIS_CONFIGURATION_PARAMETERstructure.
As an alternative to calling this function, every NDIS driver can set up configuration information in the registry for itself under the driver's Parameterskey, using an installation script.
A driver that calls this function runs at IRQL PASSIVE_LEVEL.
