_RGNDATA structure

The RGNDATA structure contains a header and an array of rectangles that compose a region. The rectangles are sorted top to bottom, left to right. They do not overlap.

Syntax

typedef struct _RGNDATA {
  RGNDATAHEADER rdh;
  char          Buffer[1];
} RGNDATA, *PRGNDATA, *NPRGNDATA, *LPRGNDATA;

Members
