NAME

       lfc_rewinddir - reset position to the beginning of a LFC directory opened by lfc_opendir in the name server

SYNOPSIS

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

       void lfc_rewinddir (lfc_DIR *dirp)

DESCRIPTION

       lfc_rewinddir resets the position to the beginning of a LFC directory opened by lfc_opendir in the name server.

       dirp   specifies the pointer value returned by lfc_opendir.

LFC_READDIR(3)						       LFC Library Functions						    LFC_READDIR(3)

NAME

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

SYNOPSIS

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

       struct dirent *lfc_readdir (lfc_DIR *dirp)

DESCRIPTION

       lfc_readdir 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.  lfc_readdir 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.

NOTE

       Only the fields d_name, d_reclen and on some platforms d_namlen are filled.

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_readdir	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_readdir, 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.
