>>TITLE XXorRegion Xlib17
XXorRegion(sra, srb, dr_return)
Region sra;
Region srb;
Region dr_return;
>>ASSERTION Good A
A call to xname computes the difference between the union and intersection of
the regions
.A sra
and
.A srb
and stores the result in
.A dr_return .
>>STRATEGY
Create regions R1 R2 R3 Ru Ri Rx using XCreateRegion.
Set R1 to a polygon using XPolygonRegion.
Set R2 to a polygon which partially intersects R1 using XPolygonRegion.
Set Ru to the union of R1 and R2 using XUnionRegion.
Set Ri to the intersection of R1 and R2 using XIntersectRegion.
Set R3 to the difference between Ru and Ri using XSubtractUnion.
Set Rx to the difference between the union and intersection of R1 and R2
using xname.
Verify that Rx is the same as R3 using XEqualRegion.
