18 The confdb_key_replace function replaces the value of a key in the con‐
19 figuration database.
20 You must specify both the key name and its value, this is because keys
21 are not unique in the database, so a value is not enough to uniqely
22 identify a key belonging to a particular parent object. Strictly,
23 even give the key name and value is not enough to uniquely identify a
24 key, If there are two (or more) keys with the same name and value, only
25 the first will have its value changed .

28 This call returns the CONFDB_OK value if successful, otherwise an error
29 is returned.

32 The errors are undocumented.
