An HDF5 group is a structure containing zero or more HDF5 objects. The two primary HDF5 objects are groups and datasets. To create a group, the calling program must:
To create a group, the calling program must call H5Gcreate. To close the group, H5Gclose must be called. The close call is mandatory.
For example:
C
Fortran
See Examples from Learning the Basics for the examples used in the Learning the Basics tutorial.
The example shows how to create and close a group. It creates a file called group.h5
in C (groupf.h5
for FORTRAN), creates a group called MyGroup in the root group, and then closes the group and file.

Shown below is the contents and the definition of the group of group.h5
(created by the C program). (The FORTRAN program creates the HDF5 file groupf.h5
and the resulting DDL shows the filename groupf.h5
in the first line.)
