[1mNAME[0m
      lfc_readdirxc  -  read  LFC directory opened by [1mlfc_opendir [22min the name
      server

[1mSYNOPSIS[0m
      [1m#include <sys/types.h>[0m
      [1m#include "lfc_api.h"[0m

      [1mstruct lfc_direnstatc *lfc_readdirxc (lfc_DIR *[4m[22mdirp[24m[1m)[0m

[1mDESCRIPTION[0m
      [1mlfc_readdirxc [22mreads the LFC directory opened by [1mlfc_opendir [22min the name
      server.   This  routine returns a pointer to a structure containing the
      current directory entry including the [1mstat [22minformation and the  comment
      associated.   [1mlfc_readdirxc  [22mcaches  a variable number of such entries,
      depending on the filename size, to minimize the number of  requests  to
      the name server.

      [4mdirp[24m   specifies the pointer value returned by [1mlfc_opendir[22m.

[1mRETURN VALUE[0m
      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, [1mserrno [22mis set appropriately.

      As  lfc_readdirxc  returns a null pointer both at the end of the direc-
      tory and on error, an application wishing to check for error situations
      should  set [1mserrno [22mto 0, then call lfc_readdirxc, then check [1mserrno [22mand
      if it is non-zero, assume an error has occurred.

[1mERRORS[0m
      [1mEBADF        [22mFile descriptor in DIR structure is invalid.

      [1mEFAULT       [4m[22mdirp[24m is a NULL pointer.

      [1mSECOMERR     [22mCommunication error.

      [1mENSNACT      [22mName server is not running or is being shutdown.
