    SYNOPSIS

           int getnetent_r(struct netent *result_buf, char *buf,
                           size_t buflen, struct netent **result,
                           int *h_errnop);
    
           int getnetbyname_r(const char *name,
                           struct netent *result_buf, char *buf,
                           size_t buflen, struct netent **result,
                           int *h_errnop);
    
           int getnetbyaddr_r(uint32_t net, int type,
                           struct netent *result_buf, char *buf,
                           size_t buflen, struct netent **result,
                           int *h_errnop);

    DESCRIPTION

           The getnetent_r(), getnetbyname_r(), and getnetbyaddr_r() functions are
           the  reentrant  equivalents  of,  respectively, getnetent(3), getnetby-
           name(3), and getnetbynumber(3).  They differ in the way that the netent
           structure is returned, and in the function calling signature and return
           value.  This manual page describes just the differences from  the  non-
           reentrant functions.
    
           Instead  of returning a pointer to a statically allocated netent struc-
           ture as the function result, these functions copy  the  structure  into
           the location pointed to by result_buf.
    
           The  buf  array  is  used  to store the string fields pointed to by the
           returned netent structure.  (The nonreentrant functions allocate  these
           strings  in  static  storage.)   The size of this array is specified in
           buflen.  If buf is too small, the call fails with the error ERANGE, and
           the  caller  must  try again with a larger buffer.  (A buffer of length
           1024 bytes should be sufficient for most applications.)
    
           If the function  call  successfully  obtains  a  network  record,  then
           *result  is  set  pointing  to result_buf; otherwise, *result is set to
           NULL.
    
           The buffer pointed to by h_errnop is used  to  return  the  value  that
           would be stored in the global variable h_errno by the nonreentrant ver-
           sions of these functions.
    
    
    

    RETURN VALUE

           On success, these functions return 0.  On error, they return one of the
           tures.
