Yes, at the level of GEOS kernal. There is no support for standard
libraries, so you can't do fopen, but kernal support is enough to do
something like:
FindFile ("filename"); to acquire file descriptor and then using data from
it:
ReadFile (dirEntryBuf.n_block, buffer, length);
or loading first block and reading byte by byte till end of file using
ReadByte();
This is more clear to people who are used to programming GEOS in asm,
using macros from geosMac and symbols from geosSym definitions, than those
with C origin. IMO programming GEOS in C is like using a high level macro
assembler.
Most likely GEOS port will not have full support for standard file
functions, because these are working at byte level and GEOS kernal prefers
loading and saving whole blocks of data.
