Function xmlTextReaderReadAttributeValue 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlTextReaderReadAttributeValue(
    reader: *mut XmlTextReader,
) -> c_int

Read the value of an attribute as a text node (attribute-value mode).

UPSTREAM-PARITY

Upstream xmlTextReaderReadAttributeValue moves the reader so that the value of the current attribute is available as a text node, returning 1 on success and 0 when already at the end. The candidate tree stores attribute values directly on the attribute node, so the value is already available via xmlTextReaderValue; report 1 when positioned on an attribute with a value.

int xmlTextReaderReadAttributeValue(xmlTextReaderPtr reader);

Safety

reader must be a valid pointer or NULL.
