Native Datatypes

Detailed Description

These are the C-like datatypes for the platform. Their names differ from other HDF5 datatype names as follows:

• Instead of a class name, precision and byte order as the last component, they have a C-like type name.
• If the type begins with U then it is the unsigned version of the integer type; other integer types are signed.
• The datatype LLONG corresponds C's long long and LDOUBLE is long double. These types might be the same as LONG and DOUBLE, respectively.
