Function xmlParserAddNodeInfo 

#[unsafe(no_mangle)]

    info: *mut _xmlParserNodeInfo,
)

Insert a node info record into the context’s sorted sequence.

UPSTREAM-PARITY

void xmlParserAddNodeInfo(xmlParserCtxtPtr ctxt, xmlParserNodeInfoPtr info);

SAFETY

• ctxt, info must be valid pointers (or NULL where the upstream C contract allows), obtained from the matching constructor/owner and not yet freed; the callee may take or keep ownership exactly as the C API specifies.

The caller must not race this call with concurrent mutation of the same objects from other threads (per-object state is not internally synchronized). Violating any of the above is undefined behavior.

Exercised by the C-API differential courts (courts/suites/data-abi/*-family-probe.c) and the CLI differential courts; those pass byte-for-byte against the upstream oracle.
