Description
Values are associated with variable names in the config block of the
RSPD configuration file. Multiple values may be associated with
a name (generally signifying an array), or just one. This function
returns an object representing one config name and its
values. If no element exists with the given name, undefined is
returned. The list of values can be retrieved with
the nextConfigData() function of this object.
Returns
A string containing the value, or
undefined if no such name exists.
In case of error, the program will croak() with an appriopriate message.
