Hello all,
I have a rt module that collects data at a relatively high rate (50Hz.)
I'm currently writing this data to a FIFO, but I would prefer to write
it to a file since the data size is quite large (~100MB per day), so I'm
wondering what options I have. Am I correct in believing that writing
to standard files in rt modules is not a good idea? Given that
assumption, I could a) write to the FIFO, have a user process
continuously read the data and rewrite it to a file (basically a copy
procedure which seems very inefficient to me), b) create a FIFO large
enough to store all the data each day or c) somehow pipe the data from
the FIFO to a file (does this circumvent the reading/writing overhead of
simply copying?) Any ideas?
cheers,
brent
