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 */
int left;
int top;
int right;
int bottom;
} RECT;For a full description of this structure, see the Microsoft Windows Programmer's Reference, Volume 3.
pt
Specifies a POINT structure that contains the specified point. The POINT structure has the following form:
typedef struct tagPOINT { /* pt */
int x;
int y;
} POINT;For a full description of this structure, see the Microsoft Windows Programmer's Reference, Volume 3.
The return value is nonzero if the point lies within the given rectangle. Otherwise, it is zero.
