LFC_GETGRPBYGIDS(3)					       LFC Library Functions					       LFC_GETGRPBYGIDS(3)

NAME

       lfc_getgrpbygids - get group names associated with given virtual gids

SYNOPSIS

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

       int lfc_getgrpbygids (int nbgroups, gid_t *gids, char **groupnames)

DESCRIPTION

       lfc_getgrpbygids gets the group names associated with given virtual gids.

       nbgroups
	      specifies the number of gids.

       gids   specifies the Virtual Group Ids.

       groupnames
	      specifies  a  buffer  to receive the pointers to the associated group names.  The buffer must be big enough to hold nbgroups pointer
	      values.  The client application is responsible for freeing the array elements when not needed anymore.

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

       ENOMEM	    Memory could not be allocated for unmarshalling the reply.

       EFAULT	    gids or groupnames is a NULL pointer.

       EINVAL	    nbgroups is not strictly positive or one of the gids does not exist in the internal mapping table.

       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.
