It is the user's responsibility to ensure that the data representation used to read data from a file is compatible with the data representation that was used to write that data to the file.
In general, using the same data representation name when writing and reading a file does not guarantee that the representation is compatible. Similarly, using different representation names on two different implementations may yield compatible representations.
Compatibility can be obtained when ``external32'' representation is used, although precision may be lost and the performance may be less than when ``native'' representation is used. Compatibility is guaranteed using "external32" provided at least one of the following conditions is met.

defines routines that support the use of
matching datatypes in heterogeneous environments and contains examples
illustrating their use.
