NAME

       lfc_readdirc - read LFC directory opened by lfc_opendir in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "lfc_api.h"

       struct lfc_direncomm *lfc_readdirc (lfc_DIR *dirp)

DESCRIPTION

       lfc_readdirc  reads  the  LFC  directory  opened  by lfc_opendir in the name server.  This
       routine returns a pointer to a structure containing the current directory entry  including
       the  comment associated.  lfc_readdirc caches a variable number of such entries, depending
       on the filename size, to minimize the number of requests to the name server.

       dirp   specifies the pointer value returned by lfc_opendir.

RETURN VALUE

       This routine returns a pointer to a structure containing the current  directory  entry  if
       the  operation  was  successful  or NULL if the end of the directory was reached or if the
       operation failed. When the end of the directory is encountered, serrno is not changed.  If
       the operation failed, serrno is set appropriately.

       As  lfc_readdirc  returns a null pointer both at the end of the directory and on error, an
       application wishing to check for error situations  should  set  serrno  to  0,  then  call
       lfc_readdirc, then check serrno and if it is non-zero, assume an error has occurred.

ERRORS

       EBADF        File descriptor in DIR structure is invalid.

       EFAULT       dirp is a NULL pointer.

       SECOMERR     Communication error.

       ENSNACT      Name server is not running or is being shutdown.
