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_getreplicax - get the replica entries associated with a LFC file in the name server

SYNOPSIS

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

       int lfc_getreplicax (const char *path, const char *guid, const char *se, int *nbentries, struct lfc_filereplicax **rep_entries)

DESCRIPTION

       lfc_getreplicax gets the replica entries associated with a LFC file in the name server.

       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.

       se     allows to restrict the replica entries to a given SE.

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

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

       struct lfc_filereplicax {
	    u_signed64	   fileid;
	    u_signed64	   nbaccesses;
	    time_t	   ctime;	  /* replica creation time */
	    time_t	   atime;	  /* last access to replica */
	    time_t	   ptime;	  /* replica pin time */
	    time_t	   ltime;	  /* replica lifetime */
	    char      r_type;	     /* 'P' for Primary, 'S' for Secondary */
	    char      status;
	    char      f_type;	     /* 'V' for Volatile, 'P' for Permanent */
	    char      setname[37];
	    char      poolname[CA_MAXPOOLNAMELEN+1];
	    char      host[CA_MAXHOSTNAMELEN+1];
	    char      fs[80];
	    char      sfn[CA_MAXSFNLEN+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 rep_entries is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    The length of guid exceeds CA_MAXGUIDLEN or the length of se exceeds CA_MAXHOSTNAMELEN 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.
