Name: H5Iget_ref
Signature:
int H5Iget_ref(hid_t obj_id)
Purpose:
Retrieves the reference count for an object.
Description:
H5Iget_ref retrieves the reference count of the object identified by obj_id.

The reference count for an object ID is attached to the information about an object in memory and has no relation to the number of links to an object on disk.

This function can also be used to check if an object ID is still valid. A non-negative return value from this function indicates that the ID is still valid.

Parameters:
Returns:
Returns a non-negative current reference count of the object ID if successful; otherwise a negative value is returned.
