void Free(void *p, int32 size)
Free memory. This will use b2Free if the size is larger than b2_maxBlockSize.
void b2CollideEdgeAndCircle(b2Manifold *manifold, const b2EdgeShape *edgeA, const b2Transform &xfA, const b2CircleShape *circleB, const b2Transform &xfB)
Compute the collision manifold between an edge and a circle.
A circle shape.

void * Allocate(int32 size)
Allocate memory. This will use b2Alloc if the size is larger than b2_maxBlockSize.
