Field Documentation

evaluate

int(*const evaluate) (struct operator*op, enum aco_option_type type, void *op_left, struct expression_token *op_right)

Evaluation function for binary operators.

Parameters

op	The operator being evaluated
type	The type of value contained in op_left
op_left	A pointer to the value to evaluate (a result or extracted from an entry)
op_right	The expression token containing the other value (a result or user-provided)

Return values

-1	error
0	evaluation is False
1	evaluation is True

evaluate_unary

int(*const evaluate_unary) (struct operator*op, enum aco_option_type type, void *operand)

Evaluation function for unary operators.

Parameters

op	The operator being evaluated
type	The type of value contained in operand
operand	A pointer to the value to evaluate

Return values

-1	error
0	evaluation is False
1	evaluation is True
