I've a client socket program that is connecting to a non-AS400 system
using SOCK_STREAM connection type.
 
This RPG program uses alarm() to break the recv() block.  Every so
often, the program seems to be receiving 0 byte from the server before
the alarm is trigger.
 
Is it possible for recv() to receive 0 byte for server?
