inet_addr API question

Here is what I used and it works just fine.

D TcpAddr                       16a   inz('10.1.1.0') 
 *---------------------------------------------------------
 * Prototype for InetAddr().                               
 *---------------------------------------------------------
D InetAddr        PR            10i 0 ExtProc('inet_addr') 
D                               16a                        

C                   EVAL      SocketId = %Trim(TcpAddr) + x'00'
C                   EVAL      rc =inetaddr(SocketId)
