pub unsafe extern "C" fn gaiaAllocGeomColl() -> gaiaGeomCollPtrExpand description
Allocates a 2D Geometry [XY]
\return the pointer to newly created Geometry object: NULL on failure
\sa gaiaFreeGeomColl
\note you are responsible to destroy (before or after) any allocated Geometry, unless you’ve passed ownership of the Geometry object to some further object: in this case destroying the higher order object will implicitly destroy any contained child object.
