[−][src]Function spatialite_sys::gaiaToSpatiaLiteBlobWkb
pub unsafe extern "C" fn gaiaToSpatiaLiteBlobWkb(
geom: gaiaGeomCollPtr,
result: *mut *mut c_uchar,
size: *mut c_int
)
Creates a BLOB-Geometry corresponding to a Geometry object
\param geom pointer to the Geometry object. \param result on completion will containt a pointer to BLOB-Geometry: NULL on failure. \param size on completion this variable will contain the BLOB's size (in bytes)
\sa gaiaFromSpatiaLiteBlobWkb, gaiaToCompressedBlobWkb
\note the BLOB buffer corresponds to dynamically allocated memory: so you are responsible to free() it [unless SQLite will take care of memory cleanup via buffer binding].
