    getnetent

    
    
    
    

    SYNOPSIS

           #include <netdb.h>
    
           struct netent *getnetent(void);
    
           struct netent *getnetbyname(const char *name);
    
           struct netent *getnetbyaddr(uint32_t net, int type);
    
           void setnetent(int stayopen);
    
           void endnetent(void);
    
    
    

    DESCRIPTION

           The getnetent()  function  reads  the  next  entry  from  the  networks
           database  and  returns  a  netent  structure  containing the broken-out
           fields from the entry.  A connection is opened to the database if  nec-
           essary.
    
           The  getnetbyname()  function  returns a netent structure for the entry
           from the database that matches the network name.
    
           The getnetbyaddr() function returns a netent structure  for  the  entry
           from  the  database  that  matches the network number net of type type.
           The net argument must be in host byte order.
    
           The setnetent() function opens a connection to the database,  and  sets
           the  next  entry  to the first entry.  If stayopen is nonzero, then the
           connection to the database will not be closed between calls to  one  of
           the getnet*() functions.
    
           The endnetent() function closes the connection to the database.
    
           The netent structure is defined in <netdb.h> as follows:
    
               struct netent {
                   char      *n_name;     /* official network name */
                   char     **n_aliases;  /* alias list */
                   int        n_addrtype; /* net address type */
                   uint32_t   n_net;      /* network number */
               }
    
           The members of the netent structure are:
    
           n_name The official name of the network.
    
           n_aliases
                  A NULL-terminated list of alternative names for the network.
    
           n_addrtype
                  The type of the network number; always AF_INET.
    
    
    

    NOTES

           In glibc versions before 2.2, the net argument of getnetbyaddr() was of
           type long.
