### DRIVERCAPS Field - ulCapsType

ulCapsType (ULONG) Defines the returned data type.

This field defines the datatype returned in pValueList, pCurrentValue, and pDefaultValue.

There are three data types currently supported, specified by the ulCapsType field: boolean, aggregate of int values, and aggregate of strings. These data types can be defined as follows:

#define CAPSTYPE_BOOLEAN 1L
#define CAPSTYPE_AGGREGATE_INT 2L
#define CAPSTYPE_AGGREGATE_STRING 3L

Note: When ulCapsType is CAPSTYPE_BOOLEAN, the driver does not have to fill in pValueList.
