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 the first piece of data associated with a given name
(NULL if no element with such a name exists). This function
would be used for elements which should be scalars (one value
for one name). Even if the user sets it multiple times, only
the first value is returned.
