Function xmlSaveClose 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlSaveClose(
    ctxt: *mut _xmlSaveCtxt,
) -> c_int

int xmlSaveClose(xmlSaveCtxt *ctxt) — flush, close and free the context.

UPSTREAM-PARITY

Returns the number of bytes written (the flush result), like upstream xmlSaveClose (xmlsave.c 2.15); the underlying output buffer is closed by xmlFreeSaveCtxt.

SAFETY

• ctxt must be a valid save context; it is freed by this call.
