NAME

       lfc_opendir - open a LFC directory in the name server

SYNOPSIS

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

       lfc_DIR *lfc_opendir (const char *path)

DESCRIPTION

       lfc_opendir  opens a LFC directory in the name server to be used in subsequent lfc_readdir operations.  A lfc_DIR structure and a buffer to
       cache the directory entries are allocated in the client API.

       path   specifies the logical pathname relative to the current LFC directory or the full LFC pathname.

RETURN VALUE

       This routine returns a pointer to be used in the subsequent directory function calls if the operation was successful or NULL if the  opera-
       tion failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    A component of path prefix does not exist or path is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix or read permission is denied on path.

       EFAULT	    path is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
