Function spatialite_sys::gaiaXmlBlobGetAbstract

pub unsafe extern "C" fn gaiaXmlBlobGetAbstract(
    blob: *const c_uchar, 
    size: c_int
) -> *mut c_char

Return the Abstract from a valid XmlBLOB buffer

\param blob pointer to the XmlBLOB buffer. \param size XmlBLOB's size (in bytes).

\return the Abstract for any valid XmlBLOB containing an Abstract; NULL in any other case.

\sa gaiaIsIsoMetadataXmlBlob, gaiaIsSldSeVectorStyleXmlBlob, gaiaIsSldSeRasterStyleXmlBlob, gaiaIsSldStyleXmlBlob

\note the returned Abstract corresponds to dynamically allocated memory: so you are responsible to free() it before or after.
