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.

LFC_GETLINKS(3) 					       LFC Library Functions						   LFC_GETLINKS(3)

NAME

       lfc_getlinks - get the link entries associated with a given file

SYNOPSIS

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

       int lfc_getlinks (const char *path, const char *guid, int *nbentries, struct lfc_linkinfo **linkinfos)

DESCRIPTION

       lfc_getlinks  gets  the	link  entries  associated with a given file.  The first entry in the list is the actual file name, while the other
       entries are the symbolic links pointing at this file.

       The file can be specified by path name or by guid.  If both are given, they must point at the same file.

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

       guid   specifies the Grid Unique IDentifier.

       nbentries
	      will be set to the number of entries in the array of link infos.

       link_entries
	      will be set to the address of an array of lfc_linkinfo structures allocated by the API. The client application  is  responsible  for
	      freeing the array when not needed anymore.

       struct lfc_linkinfo {
	    char      path[CA_MAXPATHLEN+1];
       };

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	    The named file does not exist.

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

       ENOMEM	    Memory could not be allocated for unmarshalling the reply.

       EFAULT	    path and guid are NULL pointers or nbentries or linkinfos is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    The length of guid exceeds CA_MAXGUIDLEN or path and guid are both given and they point at a different file.

       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.
