FILTERREGION structure (filter.h)

  • Article

Describes the position and extent of a specified portion of text within an object.

Syntax

typedef struct tagFILTERREGION {
  ULONG idChunk;
  ULONG cwcStart;
  ULONG cwcExtent;
} FILTERREGION;

Members

idChunk

The chunk identifier.

cwcStart

The beginning of the region, specified as an offset from the beginning of the chunk.

cwcExtent

The extent of the region, specified as the number of Unicode characters.

Remarks

The cwcExtent member might specify a number of characters (starting from a position the cwcStart member specifies) that extends beyond the end of the chunk. In that case, the region should be continued into the next chunk, which should have the same attribute as the current region.
