save/load with pipes

[Daniel Kraft]

Hi!

In one of my codes, I'm using fork to split processing of my data set
onto multiple processes.  The subprocesses send their results back via
temporary files and the save/load mechanism for simplicity.  It would be
much cleaner to use pipes instead.  But since the pipe() function
returns a pair of file descriptors, I wonder whether one can use
save/load (or a similar high-level function which serialises the data
for me) also with file descriptors and not just with file names.  Is
there a way to do that?

(My code is basically a custom implementation of parcellfun, so maybe
I'll switch to parcellfun in the future anyway.  But I still believe
this is something interesting to know in case I need a communication
tool like this in the future for something else.)

Yours,
Daniel
