pub fn functions(
program: &Program,
qualify: Qualify,
errors: &mut Vec<Error>,
) -> Vec<Udf>Expand description
The functions a program may invoke, each laid out once. A prototype that does not lay out is left out here: compiling it reports why, and an invocation of it is then unknown. One named as an intrinsic function is left out unless the REPOSITORY paragraph names it, as the name then invokes the intrinsic function (assumption C271).
