.TH CONFDB_OBJECT_FIND 3 2008-04-17 "corosync Man Page" "Corosync Cluster Engine Programmer's Manual"
.SH NAME
confdb_object_find \- Find a named object in the Configuration Database
.SH SYNOPSIS
.B #include <corosync/confdb.h>
.sp
.BI "confdb_error_t confdb_object_find_start(confdb_handle_t " handle ", unsigned int " parent_object_handle " ); "
.sp
.BI "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 " ); "
.sp
.BI "confdb_error_t confdb_object_find_destroy(confdb_handle_t " handle ", unsigned int " parent_object_handle " ); "
.SH DESCRIPTION
The
.B confdb_object_find
function repeatedly returns objects that match a given name. You must call
.B 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
.B 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.
.BR
You need to provide the same object name and length for each call to
.B confdb_object_find,
If you change either of then, the results are undefined.
.BR
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
.B confdb_object_iter
or
.B confdb_key_iter
calls on the same parent object.
.BR
.B When you have finished searching for objects, call the
.B confdb_object_find_destroy
library call to free up memory associated with the search context.
.SH RETURN VALUE
This call returns the CONFDB_OK value if successful, otherwise an error is returned.
.PP
.SH ERRORS
The errors are undocumented.
