.SH DESCRIPTION
This function is used to clip a line segment to a rectangle\[char46] A line segment
contained entirely within the rectangle or that does not intersect will
remain unchanged\[char46] A line segment that crosses the rectangle at either or
both ends will be clipped to the boundary of the rectangle and the new
coordinates saved in
.BR X1
,
.BR Y1
,
.BR X2
, and/or
.BR Y2
as necessary\[char46]

.SH FUNCTION PARAMETERS
.TP
.I rect
an 
.BR SDL_FRect
 structure representing the rectangle to intersect
.TP
.I X1
a pointer to the starting X-coordinate of the line
.TP
.I Y1
a pointer to the starting Y-coordinate of the line
.TP
.I X2
a pointer to the ending X-coordinate of the line
.TP
.I Y2
a pointer to the ending Y-coordinate of the line
.SH RETURN VALUE
Returns 
.BR SDL_TRUE
 if there is an intersection,

.BR SDL_FALSE
 otherwise\[char46]

.SH AVAILABILITY
This function is available since SDL 3\[char46]0\[char46]0\[char46]
