pub fn read_cond_num() -> Option<i64>Expand description
Read an integer from the next cond token. NOT a direct C port —
the C get_cond_num(char *tst) (parse.c:2643) is the
string-lookup helper ported below. This Rust-only helper exists
to support the AST cond-walker (par_cond_* analogs) when it
needs a numeric literal from the current lex position.
