LFC_CLOSEDIR(3) 					       LFC Library Functions						   LFC_CLOSEDIR(3)

NAME

       lfc_closedir - close LFC directory opened by lfc_opendir in the name server

SYNOPSIS

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

       int lfc_closedir (lfc_DIR *dirp)

DESCRIPTION

       lfc_closedir closes the LFC directory opened by lfc_opendir in the name server and frees the lfc_DIR structure pointed by dirp.

       dirp   specifies the pointer value returned by lfc_opendir.

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

       EBADF	    File descriptor in DIR structure is invalid.

       EFAULT	    dirp is a NULL pointer.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

LFC_READDIRXR(3)					       LFC Library Functions						  LFC_READDIRXR(3)

NAME

       lfc_readdirxr - read LFC directory opened by lfc_opendir in the name server

SYNOPSIS

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

       struct lfc_direnrep *lfc_readdirxr (lfc_DIR *dirp, char *se)

DESCRIPTION

       lfc_readdirxr  reads  the LFC directory opened by lfc_opendir in the name server.  This routine returns a pointer to a structure containing
       the current directory entry (basename, guid and filesize) and the replica information.

       struct lfc_rep_info {
	    u_signed64	   fileid;
	    char      status;
	    char      *host;
	    char      *sfn;
       };

       struct lfc_direnrep {
	    u_signed64	   fileid;
	    char      guid[CA_MAXGUIDLEN+1];
	    mode_t	   filemode;
	    u_signed64	   filesize;
	    int       nbreplicas;
	    struct lfc_rep_info *rep;	  /* array of replica info structures */
	    unsigned short d_reclen; /* length of this entry */
	    char      d_name[1];     /* basename in variable length */
       };

       lfc_readdirxr caches a variable number of such entries, depending on the filename size, to minimize the number  of  requests  to  the  name
       server.

       dirp   specifies the pointer value returned by lfc_opendir.

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

RETURN VALUE

       This  routine returns a pointer to a structure containing the current directory entry if the operation was successful or NULL if the end of
       the directory was reached or if the operation failed. When the end of the directory is encountered, serrno is not changed. If the operation
       failed, serrno is set appropriately.

       As lfc_readdirxr returns a null pointer both at the end of the directory and on error, an application wishing to check for error situations
       should set serrno to 0, then call lfc_readdirxr, then check serrno and if it is non-zero, assume an error has occurred.

ERRORS

       EBADF	    File descriptor in DIR structure is invalid.

       ENOMEM	    Memory could not be allocated for unmarshalling the reply.

       EFAULT	    dirp is a NULL pointer.

       EINVAL	    The length of se exceeds CA_MAXHOSTNAMELEN.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
