IO_RESOURCE_LIST structure (miniport.h)
The IO_RESOURCE_LIST structure describes a range of raw hardware resources, of various types, that can be used by a device. The resources specified represent a single, acceptable resource configuration for a device. An array of IO_RESOURCE_LIST structures is contained within each IO_RESOURCE_REQUIREMENTS_LIST structure.
Syntax
typedef struct _IO_RESOURCE_LIST {
USHORT Version;
USHORT Revision;
ULONG Count;
IO_RESOURCE_DESCRIPTOR Descriptors[1];
} IO_RESOURCE_LIST, *PIO_RESOURCE_LIST;
Members
Version
The version number of this structure. This value should be 1.
Revision
The revision of this structure. This value should be 1.
Count
The number of elements in the Descriptors array.
Descriptors[1]
The first element in an array of one or more IO_RESOURCE_DESCRIPTOR structures.
Remarks
This structure is the header for an array of IO_RESOURCE_DESCRIPTOR structures. The Descriptors member contains the first element in this array, and the Count member specifies the total number of array elements. If the array contains more than one element, the remaining elements in the array immediately follow the IO_RESOURCE_LIST structure in memory. The total number of bytes occupied by the IO_RESOURCE_LIST structure and any array elements that follow this structure is sizeof(IO_RESOURCE_LIST) + (Count - 1) * sizeof(IO_RESOURCE_DESCRIPTOR).
