[−][src]Function spatialite_sys::gaiaAllocGeomCollXYM
pub unsafe extern "C" fn gaiaAllocGeomCollXYM() -> gaiaGeomCollPtr
Allocates a 2D Geometry [XYM]
\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.
