92Routine Description:
93
94 This routine is used to read back various registry values.
95
96Arguments:
97
98 HwDeviceExtension
99 Supplies a pointer to the miniport's device extension.
100
101 Context
102 Context value passed to the get registry parameters routine.
103 If this is not null assume it's a ULONG* and save the data value in it.
104
105 ValueName
106 Name of the value requested.
107
108 ValueData
109 Pointer to the requested data.
110
111 ValueLength
112 Length of the requested data.
113
114Return Value:
115
116 If the variable doesn't exist return an error,
117 else if a context is supplied assume it's a PULONG and fill in the value
118 and return no error, else if the value is non-zero return an error.
