Function xmlXPathContextSetCache 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlXPathContextSetCache(
    ctxt: *mut _xmlXPathContext,
    active: c_int,
    _value: c_int,
    _options: c_int,
) -> c_int

int xmlXPathContextSetCache(xmlXPathContextPtr ctxt, int active, int value, int options).

The candidate has no object cache; the call is accepted and recorded (active ⇒ a marker in ctxt->cache), returning 0 on success.

SAFETY

• ctxt must be a valid context or NULL.
