H5F.get_obj_ids

List of open HDF5 file objects

Syntax

[num_obj_ids,obj_id_list] = H5F.get_obj_ids(file_id,types,max_objs)

Description

[num_obj_ids,obj_id_list] = H5F.get_obj_ids(file_id,types,max_objs) returns a list of all open identifiers for HDF5 objects of the type specified by types in the file specified by file_id. The max_objs input specifies the maximum number of object identifiers to return. num_obj_ids is the total number of objects in the list. types can be specified by one of the following character vectors:

'H5F_OBJ_FILE'
'H5F_OBJ_DATASET'
'H5F_OBJ_GROUP'
'H5F_OBJ_DATATYPE'
'H5F_OBJ_ATTR'
'H5F_OBJ_ALL'
'H5F_OBJ_LOCAL'

Examples

fid = H5F.open('example.h5');
gid1 = H5G.open(fid,'/g1');
gid2 = H5G.open(fid,'/g2');
gid3 = H5G.open(fid,'/g3');
gid4 = H5G.open(fid,'/g4');
[num_obj_ids,objs] = H5F.get_obj_ids(fid,'H5F_OBJ_GROUP',3);
H5G.close(gid1);
H5G.close(gid2);
H5G.close(gid3);
H5G.close(gid4);
H5F.close(fid);
