Function xmlTextWriterClose 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlTextWriterClose(
    writer: *mut XmlTextWriter,
) -> c_int

Close the writer’s output buffer. The writer itself is NOT freed (upstream contract: xmlFreeTextWriter does that). Returns XML_ERR_OK (0) on success, XML_ERR_ARGUMENT (9) for a NULL writer or NULL output buffer.

UPSTREAM-PARITY

int xmlTextWriterClose(xmlTextWriterPtr writer);

SAFETY

• writer must be a valid pointer to an XmlTextWriter or NULL.
