| BOOL PtInRect(lprc, pt) | |||||
| CONST RECT *lprc; | /* address of structure with rectangle | */ | |||
| POINT pt; | /* structure with point | */ | |||
The PtInRect function determines whether the specified point lies within a given rectangle. A point is within a rectangle if it lies on the left or top side or is within all four sides. A point on the right or bottom side is considered outside the rectangle.
lprc
Points to a RECT structure that contains the specified rectangle. The RECT structure has the following form:
typedef struct tagRECT { /* rc */
LONG left;
LONG top;
LONG right;
LONG bottom;
} RECT;
pt
Specifies a POINT structure that contains the specified point. The POINT structure has the following form:
typedef struct tagPOINT { /* pt */
LONG x;
LONG y;
} POINT;
The return value is TRUE if specified point lies within the given rectangle. Otherwise, it is FALSE.
