.BI "confdb_error_t confdb_key_replace(confdb_handle_t " handle ", unsigned int " parent_object_handle ", void " *key_name ",
.BI	int " key_name_len ",
.BI	void " *old_value ",
.BI	int " old_value_len ",
.BI	void " *new_value ",

.SH DESCRIPTION
The
.B confdb_key_replace
function replaces the value of a key in the configuration database.
.br
You must specify both the key name and its value, this is because keys are not
unique in the database, so a value is not enough to uniqely identify a key belonging
to a particular parent object.
.BR
Strictly, even give the key name and value is not enough to uniquely identify a key,
If there are two (or more) keys with the same name and value, only the first will have 
its value changed .
.SH RETURN VALUE
This call returns the CONFDB_OK value if successful, otherwise an error is returned.
.PP
.SH ERRORS
The errors are undocumented.
