NAME

6       lfc_readdirxc  -  read  LFC directory opened by lfc_opendir in the name
7       server
8

SYNOPSIS

10       #include <sys/types.h>
11       #include "lfc_api.h"
12
13       struct lfc_direnstatc *lfc_readdirxc (lfc_DIR *dirp)
14

DESCRIPTION

16       lfc_readdirxc reads the LFC directory opened by lfc_opendir in the name
17       server.   This  routine returns a pointer to a structure containing the
18       current directory entry including the stat information and the  comment
19       associated.   lfc_readdirxc  caches  a variable number of such entries,
20       depending on the filename size, to minimize the number of  requests  to
21       the name server.
22
23       dirp   specifies the pointer value returned by lfc_opendir.
24

RETURN VALUE

26       This  routine  returns  a pointer to a structure containing the current
27       directory entry if the operation was successful or NULL if the  end  of
28       the  directory  was reached or if the operation failed. When the end of
29       the directory is encountered, serrno is not changed. If  the  operation
30       failed, serrno is set appropriately.
31
32       As  lfc_readdirxc  returns a null pointer both at the end of the direc‐
33       tory and on error, an application wishing to check for error situations
34       should  set serrno to 0, then call lfc_readdirxc, then check serrno and
35       if it is non-zero, assume an error has occurred.
36

ERRORS

38       EBADF        File descriptor in DIR structure is invalid.
39
40       EFAULT       dirp is a NULL pointer.
41
42       SENOSHOST    Host unknown.
43
44       SENOSSERV    Service unknown.
45
46       SECOMERR     Communication error.
47
48       ENSNACT      Name server is not running or is being shutdown.
