Hi,
I'm looking at the functions for sending/receiving over a
datagram-based socket, and I'm confused about the return value of
recvfrom.
val recvfrom : file_descr -> string -> int -> int -> msg_flag list ->
int * sockaddr
What is the int value returned? The bytes actually read?
Jonathan

Have a look at the code in otherlibs/unix/sendrecv.c:unix_recvfrom.
The int is the return value from recvfrom(2), which is the number of
bytes received, or 0 if the peer has performed a shutdown.
