NAME
       getservent, getservbyname, getservbyport - get service entry
 
SYNOPSIS
       #include &lt;network.h&gt;
 
       struct servent *getservbyname(const char *name, const char *proto);
 
       struct servent *getservbyport(int port, const char *proto);
 
DESCRIPTION
       The  getservbyname()  function returns a servent structure
       for the line from /etc/services that matches  the  service
       name using protocol proto.
 
       The  getservbyport()  function returns a servent structure
       for the line that matches the port port given  in  network
       byte order using protocol proto.
 
       The servent structure is defined in &lt;netdb.h&gt; as follows:
 
              struct servent {
                      char    *s_name;        /* official service name */
                      char    **s_aliases;    /* alias list */
                      int     s_port;         /* port number */
                      char    *s_proto;       /* protocol to use */
              }
 
       The members of the servent structure are:
 
       s_name The official name of the service.
 
       s_aliases
              A zero terminated list of alternative names for the
              service.
 
       s_port The  port  number  for the service given in network
              byte order.
 
       s_proto
              The name of the protocol to use with this  service.
 
RETURN VALUE
       The   getservbyname()  and  getservbyport()
       functions return the servent structure, or a NULL  pointer
       if an error occurs.
