Name: H5Topen2
Signature:
  hid_t `H5Topen2`( hid_t `loc_id`, const char * `name`, hid_t `tapl_id` )

Purpose:
  Opens a committed (named) datatype.

Description:
  `H5Topen2` opens a committed datatype at the location specified by `loc_id` and returns an identifier for the datatype. `loc_id` is either a file or group identifier. The identifier should eventually be closed by calling `H5Tclose` to release resources.

  The committed datatype is opened with the datatype access property list `tapl_id`.

Parameters:

hid_t `loc_id` | IN: A file or group identifier.
const char * `name` | IN: A datatype name, defined within the file or group identified by `loc_id`.
hid_t `tapl_id` | IN: Datatype access property list identifier.

Returns:
  Returns a committed datatype identifier if successful; otherwise returns a negative value.

Fortran90 Interface: See listing under `H5Topen`.
