The environment variable is used in preference * to the cpp constant. If neither is defined then use some default value. * * HDF5_DRIVER: This string describes what low level file driver to * use for HDF5 file access. The first word in the * value is the name of the driver and subsequent data * is interpreted according to the driver. See * h5_fileaccess() for details. * * HDF5_PREFIX: A string to add to the beginning of all serial test * file names. This can be used to run tests in a * different file system (e.g., "/tmp" or "/tmp/myname"). * The prefix will be separated from the base file name * by a slash. See h5_fixname() for details. *
