RGNDATA structure (wingdi.h)
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
rdh
A RGNDATAHEADER structure. The members of this structure specify the type of region (whether it is rectangular or trapezoidal), the number of rectangles that make up the region, the size of the buffer that contains the rectangle structures, and so on.
Buffer[1]
Specifies an arbitrary-size buffer that contains the RECT structures that make up the region.
