Expand description

long xmlTextReaderByteConsumed(xmlTextReaderPtr reader).

Returns the total bytes consumed from the input (0 when unavailable — the candidate parses the full input up front; documented divergence).

§SAFETY

  • reader 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.
