DESCRIPTION
12
       The  getservbyname()  function returns a servent structure
13
       for the line from /etc/services that matches  the  service
14
       name using protocol proto.
15
 
16
       The  getservbyport()  function returns a servent structure
17
       for the line that matches the port port given  in  network
18
       byte order using protocol proto.
19
 
20
       The servent structure is defined in <netdb.h> as follows:
21
 
22
              struct servent {
23
                      char    *s_name;        /* official service name */
24
                      char    **s_aliases;    /* alias list */
25
                      int     s_port;         /* port number */
26
                      char    *s_proto;       /* protocol to use */
27
              }
28
 
29
       The members of the servent structure are:
30
 
31
       s_name The official name of the service.
32
