RESDIR structure

Contains information about an individual icon or cursor component in a RT_GROUP_ICON or RT_GROUP_CURSOR resource group.

There is one RESDIR structure for each group component.

The structure definition provided here is for explanation only; it is not present in any standard header file.

Syntax

typedef struct {
  union
  {
      ICONRESDIR   Icon;
      CURSORDIR    Cursor;
  };
  WORD       Planes;
  WORD       BitCount;
  DWORD      BytesInRes;
  WORD       IconCursorId;
} RESDIR;

Members

Icon

Type: ICONRESDIR

The width, height, and color count of the indicated icon.

Cursor

Type: CURSORDIR

The width and height of the indicated cursor.

Planes

Type: WORD

The number of color planes in the icon or cursor bitmap.

BitCount

Type: WORD

The number of bits per pixel in the icon or cursor bitmap.

BytesInRes

Type: DWORD

The size of the resource, in bytes.

IconCursorId

Type: WORD

Unique ordinal identifier of the RT_ICON icon or RT_CURSOR cursor resource.

Remarks

One or more RESDIR structures immediately follow the NEWHEADER structure in the .res file. The ResCount member of the NEWHEADER structure specifies the number of RESDIR structures. Note that the RESDIR structure consists of either an ICONRESDIR structure or a CURSORDIR structure followed by the Planes, BitCount, BytesInRes, and IconCursorId members.

If the RESDIR structure contains information about a cursor, the first two WORDs the resource compiler writes to the RT_CURSOR resource are the xHotSpot and yHotSpot members of the LOCALHEADER structure.
