Michael Walsh3e26e102017-01-10 11:29:28 -0600[diff] [blame]20 Validate a robot value.
21
22 This function is the robot wrapper for gen_robot_print.svalid_value.
Michael Walsh18176322016-11-15 15:11:21 -0600[diff] [blame]23
24 Description of arguments:
25 var_name The name of the variable whose value is to
26 be validated.
27 invalid_values A list of invalid values. If var_value is
28 equal to any of these, it is invalid.
29 Note that if you specify anything for
30 invalid_values (below), the valid_values
31 list is not even processed.
32 valid_values A list of invalid values. var_value must
33 be equal to one of these values to be
34 considered valid.

36 Examples of robot calls and corresponding output:
