CONFDB_KEY_ITER(3)
NAME
confdb_key_iter - Iterate through key/value pairs in the Configuration
Database
SYNOPSIS
#include <corosync/confdb.h> confdb_error_t confdb_key_iter_start(confdb_handle_t handle, unsigned int parent_object_handle ); confdb_error_t confdb_key_iter(confdb_handle_t handle, unsigned int parent_object_handle, void *key_name, int *key_name_len, void *value, int *value_len );
DESCRIPTION
The confdb_key_iter function repeatedly returns all key/value pairs
that are subobjects of the specified parent. You must call
confdb_key_iter_start first. This establishes a context for the parent
object so that it knows where you are in the list. Then the next call
to confdb_key_iter will return the first key/value in the list. Subsequent calls will return any remaining keys. The function returns
CONFDB_ERR_ACCESS when the all of the matching keys have been seen.
The library holds a seperate context for each parent object, so you can
call confdb_key_iter() on several parent objects at the same time and
they will not interfere. Nor will they interfere with
confdb_object_find or confdb_object_iter calls on the same parent
object.
RETURN VALUE
This call returns the CONFDB_OK value if successful, otherwise an error
is returned.
ERRORS
The errors are undocumented.
