<h1>Introduction</h1>
FlexIO is a compact API for storing multidimensional scientific
data. It hides the differences between underlying file formats
including
<a href="http://hdf.ncsa.uiuc.edu">HDF-SDS</a>,
<a href="IEEEIO.html">IEEEIO</a>, and network socket connections.
(<i>Support for HDF5 will be added soon</i>). It is designed to
allow you to use exactly the same subroutine/method calls to store
your data regardless of the underlying file format.
FlexIO includes C++, C, and Fortran77/F90 interfaces and it has
been ported to Sun-Solaris, Digital Unix, Cray-Unicos, SGI-Irix
(32 and 64 bit), Windows95 and NT.<p>
FlexIO borrows its terminology and storage-style from
<a href="http://hdf.ncsa.uiuc.edu">HDF and NetCDF</a>.
The file stores a sequence of multidimesional
arrays which are referred to generically as <b>datasets</b>.
The dimensions and datatype are stored with each dataset so that
the data is completely self-describing. In addition,
NetCDF-style named attributes can be stored with each dataset to
add information like coordinates, units, and other auxillary
information.<p>
A set of higher level API's sit on top of FlexIO which permit
simplified access to complex datastructures like Finite-Element,
Adaptive Mesh Refinement, and Unigrid datastructures. In
addition the MPIO interface provides access to parallel IO for
MPI codes.<p>
