H5Pget_family_offset (
hid_t fapl_id,
hsize_t *offset
)
H5Pget_family_offset retrieves the value of
offset from the file access property list
fapl_id so that the user application
can retrieve a file handle for low-level access to a particular member
of a family of files. The file handle is retrieved with a separate
call to H5Fget_vfd_handle
(or, in special circumstances, to H5FDget_vfd_handle;
see Virtual File Layer and
List of VFL Functions
in HDF5 Technical Notes).
The data offset returned in offset is the offset
of the data in the HDF5 file that is stored on disk in the selected
member file in a family of files.
Use of this function is only appropriate for an HDF5 file written as a
family of files with the FAMILY file driver.
