Name: H5Rdereference
Signature:
hid_t H5Rdereference(hid_t obj_id, H5R_type_t ref_type, void *ref )
Purpose:
Opens the HDF5 object referenced.
Description:
Given a reference, ref, to an object or a region in an object, H5Rdereference opens that object and returns an identifier.

The parameter obj_id must be a valid identifier for an object in the HDF5 file containing the referenced object, including the file identifier.

The parameter ref_type specifies the reference type of the reference ref. ref_type may contain either of the following values:

Parameters:
Returns:
Returns identifier of referenced object if successful; otherwise returns a negative value.
Fortran90 Interface: h5rdereference_f
