CONFDB_OBJECT_FIND(3)
NAME
confdb_object_find - Find a named object in the Configuration Database
SYNOPSIS
#include <corosync/confdb.h> confdb_error_t confdb_object_find_start(confdb_handle_t handle, unsigned int parent_object_handle ); confdb_error_t confdb_object_find(confdb_handle_t handle, unsigned int parent_object_handle, void *object_name, int object_name_len, unsigned int *object_handle ); confdb_error_t confdb_object_find_destroy(confdb_handle_t handle, unsigned int parent_object_handle );
DESCRIPTION
The confdb_object_find function repeatedly returns objects that match a
given name. You must call confdb_object_find_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_object_find will return the
handle of the first object that matches the passed in name. Subsequent
calls will return any remaining objects with the same name. The function returns CONFDB_ERR_ACCESS when the all of the matching objects
have been seen. You need to provide the same object name and length
for each call to confdb_object_find, If you change either of then, the
results are undefined. The library holds a seperate context for each
parent object, so you can call confdb_object_iter() on several parent
objects at the same time and they will not interfere. Nor will they
interfere with confdb_object_iter or confdb_key_iter calls on the same
parent object. When you have finished searching for objects, call the
confdb_object_find_destroy library call to free up memory associated
with the search context.
RETURN VALUE
This call returns the CONFDB_OK value if successful, otherwise an error
is returned.
ERRORS
The errors are undocumented.
