 The first line allocates an instance `coder` that holds the settings and operations for compression. The first four function arguments describe the number of elements in each dimension of the original data set, which can have up to four dimensions. Data sets with less than four dimensions pass `1` for the unused dimensionality. The parameter `nPar` is a count for the number of independent parameters that can be stacked inside the data set. The function argument `precision` passes the precision of the data set that can take one of three values `bwc_precision_half`, `bwc_precision_single`, and `bwc_precision_double`. After allocation, the `coder` can be reused for multiple data sets that are described by the same dimensionality, number of parameters, and floating point precision.
 
 The second line initializes the `bwc_stream` that handles the data set and the resulting compressed bitstream. The incoming pointers `orig_in` and `comp_out` must be managed by the user. This way, the BWC can be used on-the-fly for in-memory compression using readily existing pointers and buffers from the user applications. The argument `comp` is of type `bwc_mode` and classifies the `stream` to be input for compression.

 bwc_codec *decoder = bwc_alloc_decoder();

 Allocation of a `bwc_codec` for decompression, in the first line, is considerably simpler than for compression because the properties dimensionality, number of parameter, and precision of the original data set is encoded in the header of a compressed `bwc_stream`. 
 
 The second line passes the incoming, compressed stream as the pointer `comp_in` and provides a user defined buffer `decomp_out` for the decompressed output. The `decomp` flag signals the mode of the `stream` to be decompressed.
