Replace a key/value pair from the configuration database
#include <corosync/confdb.h>
confdb_error_t confdb_key_replace(confdb_handle_t handle, unsigned int parent_object_handle, void *key_name, int key_name_len , void *old_value , int old_value_len , void *new_value , int new_value_len );
The confdb_key_replace function replaces the value of a key in the configuration database.
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.
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 .
This call returns the CONFDB_OK value if successful, otherwise an error is returned.
The errors are undocumented.
