NAME¶

confdb_key_replace - Replace a key/value pair from the Configuration Database

SYNOPSIS¶

#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 );

DESCRIPTION¶

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 .

RETURN VALUE¶

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

ERRORS¶

The errors are undocumented.
