RE: socket api question - is it possible for recv() to receive 0byte from server?

Cool!  Thanks.

One more question:
What is the proper way to check for alarm().  
 C                   eval      recvlen = recv(hostSock :%addr(recvData)
 C                                           :%size(recvData)-10       
 C                                           :0)                       
  *       disable timeout                                              
 C                   callp     alarm(0)                                
                                                                       
  *       leave if timeout occur                                       
 C                   if        recvLen <= 0 and (errno = EINTR)        
 C                   leave                                              
 C                   endif


Should I even check the recvLen?  
Should I replace 
 C                   if        recvLen <= 0 and (errno = EINTR)        
with
 C                   if        errno = EINTR        

Thanks

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?
