LFC_OPENDIRG(3) 					       LFC Library Functions						   LFC_OPENDIRG(3)

NAME

       lfc_opendirg - open a LFC directory, having the specified GUID, in the name server

SYNOPSIS

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

       lfc_DIR *lfc_opendirg (const char *path, const char *guid)

       lfc_DIR *lfc_opendirxg (char *server, const char *path, const char *guid)

DESCRIPTION

       lfc_opendirg  opens  a  LFC  directory,	having the specified GUID, in the name server to be used in subsequent lfc_readdirg operations.  A
       lfc_DIR structure and a buffer to cache the directory entries are allocated in the client API.

       guid   specifies the Grid Unique IDentifier.

       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.

       EINVAL	    The length of the guid component exceeds CA_MAXGUIDLEN.

       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.

NAME

       lfc_creatg - create a new LFC file with the specified GUID or reset it in the name server

SYNOPSIS

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

       int lfc_creatg (const char *path,  const char *guid, mode_t mode)

DESCRIPTION

       lfc_creatg creates a new LFC file with the specified GUID or resets it in the name server.

       If the file exists, the length is truncated to 0 and the mode and owner are unchanged.

       If  the file does not exist yet, an entry is created in the name server database and the file's owner ID is set to the effective user ID of
       the requestor.  The group ID of the file is set to the effective group ID of the requestor or is taken from the	parent	directory  if  the
       latter has the S_ISGID bit set.

       The  access permission bits for the file are taken from mode, then all bits set in the requestor's file mode creation mask are cleared (see
       lfc_umask(3)).

       guid   specifies the Grid Unique IDentifier.

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

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation 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 the file does not exist and write permission  on  the  parent
		    directory is denied or the file exists and write permission on the file itself is denied.

       EFAULT	    path is a NULL pointer.

       EEXIST	    File exists already with a different GUID or has replicas.

       ENOTDIR	    A component of path prefix is not a directory.

       EISDIR	    path is an existing directory.

       EINVAL	    The fileclass in the parent directory is zero or the length of the guid exceeds CA_MAXGUIDLEN.

       ENOSPC	    The name server database is full.

       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.
