data is the data stored in the blob field of the db file.
len is the length of that field. The function hides everything needed
for evaluating the field data. It can handle both single blob blocks and
suballocated blocks.

PX_set_blob_file(3) and
PX_get_data_blob(3) or
PX_get_data_graphic(3) instead.
