Well I have done similar things recently.
The Unix library provides more or less unix system calls,
so I use man 2...

In your case, if I understand well.

First, ignore SIGPIPE, we are real hackers, we look at return codes
of every IO operation (in C).

In Caml, it's something like :
Sys.set_signal Sys.sigpipe Sys.Signal_ignore 


Then, write, flush, printf etc. should normally return some error
code.

In C, you then need to have a look at the errno variable.
In Caml this means raising some exception, namely Sys_error "message".

To get information on those error codes, you can do ``man 2 write''
for instance. The "message" string gives a readable (?) interpretation
of the error code.


Hope this helps. Apologize for any over-simplification.
