NAME

confdb_key_delete - Delete a key/value pair from the Configuration Database

SYNOPSIS

#include <corosync/confdb.h>

confdb_error_t confdb_key_delete(confdb_handle_t handle, unsignedint parent_object_handle , void *key_name , int key_name_len , void *value , int value_len );

DESCRIPTION

The confdb_key_delete function removes a key/value pair from 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,evengivethekeynameandvalueisnotenoughtouniquelyidentifyakey, If there are two (or more) keys with the same name and value, only the first will be deleted.

RETURN VALUE

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

ERRORS

The errors are undocumented.
