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 ,
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.
