[1mNAME[0m
      lfc_readdirc  -  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_direncomm *lfc_readdirc (lfc_DIR *[4m[22mdirp[24m[1m)[0m

[1mDESCRIPTION[0m
      [1mlfc_readdirc [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 comment associated.  [1mlfc_readdirc[0m
      caches  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_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 [1mserrno [22mto 0, then call lfc_readdirc, 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.
