Function xmlStringCurrentChar 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlStringCurrentChar(
    ctxt: *mut _xmlParserCtxt,
    cur: *const xmlChar,
    len: *mut c_int,
) -> c_int

Decode the current character starting at cur (upstream parserInternals.c xmlStringCurrentChar).

UPSTREAM-PARITY

int xmlStringCurrentChar(xmlParserCtxt *ctxt, const xmlChar *cur, int *len);

Returns the character value (as a UCS-4 code point) and sets *len to the number of bytes consumed. Returns 0 (with *len = 0) on error or NULL arguments. The upstream implementation ignores ctxt (it only influences encoding detection, and the candidate is UTF-8 only), so it is unused here as well.

SAFETY

• cur must be a valid pointer into a NUL-terminated byte string (a single NUL-terminated buffer suffices; the byte length is probed through *len, initialized to 4 as upstream).
• len must be a valid int*.
