[−][src]Function spatialite_sys::gaiaAllocPointXYZM
pub unsafe extern "C" fn gaiaAllocPointXYZM(
x: f64,
y: f64,
z: f64,
m: f64
) -> gaiaPointPtr
Allocates a 3D POINT [XYZM]
\param x the X coordinate. \param y the Y coordinate. \param z the Z coordinate. \param m the M measure.
\return the pointer to the newly created POINT object: NULL on failure
\sa gaiaFreePoint
\note you are responsible to destroy (before or after) any allocated POINT, unless you've passed ownership of the POINT object to some further object: in this case destroying the higher order object will implicitly destroy any contained child object.
