LFC_SETFSIZE(3) 					       LFC Library Functions						   LFC_SETFSIZE(3)

NAME

       lfc_setfsize - set filesize for a regular file; set also last modification time to the current time

SYNOPSIS

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

       int lfc_setfsize (const char *path, struct lfc_fileid *file_uniqueid, u_signed64 filesize)

       int lfc_setfsizec (const char *path, struct lfc_fileid *file_uniqueid, u_signed64 filesize, const char *csumtype, char *csumvalue)

DESCRIPTION

       lfc_setfsize  sets  the filesize for a regular file; set also the last modification time to the current time.  This function should only be
       called by the stager after the last write operation has been performed on the file.  The  file  can  be	identified  by	path  name  or	by
       file_uniqueid.  If both are specified, file_uniqueid is used.

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

       csumtype
	      specifies the type of checksum. Valid types are:

	      CS     standard 32 bits checksum

	      AD     Adler 32 bits checksum

	      MD     MD5 128 bits checksum

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 caller effective user ID does not match the owner ID of
		    the file or write permission on the file itself is denied.

       EFAULT	    path and file_uniqueid are NULL pointers.

       ENOTDIR	    A component of path prefix is not a directory.

       EISDIR	    The file is not a regular file.

       EINVAL	    The length of the csumtype exceeds 2 or csumtype is an unknown type or the length of the csumvalue exceeds 32.

       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_STAT(3)						       LFC Library Functions						       LFC_STAT(3)

NAME

       lfc_stat - get information about a LFC file or directory in the name server

SYNOPSIS

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

       int lfc_lstat (const char *path, struct lfc_filestat *statbuf)

       int lfc_stat (const char *path, struct lfc_filestat *statbuf)

       int lfc_statx (const char *path, struct lfc_fileid *file_uniqueid, struct lfc_filestat *statbuf)

DESCRIPTION

       lfc_stat gets information about a LFC file or directory in the name server.

       lfc_lstat  is  identical to lfc_stat except for symbolic links.	lfc_lstat retrieves information about the link itself, while lfc_stat gets
       information about the file/directory referenced by the symbolic link.

       lfc_statx returns the same information plus the file unique id (name server hostname and file id).  The file can be specified by path  name
       or by file_uniqueid.  If both are given, file_uniqueid is used.

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

       The structure pointed to by statbuf contains the following members:
	      u_signed64     fileid;	    /* entry unique identifier */
	      mode_t	     filemode; /* see below */
	      int	nlink;	       /* number of files in a directory */
	      uid_t	     uid;
	      gid_t	     gid;
	      u_signed64     filesize;
	      time_t	     atime;	    /* last access to file */
	      time_t	     mtime;	    /* last file modification */
	      time_t	     ctime;	    /* last metadata modification */
	      short	     fileclass; 	 /* 1--> experiment, 2 --> user */
	      char	status;        /* '-' --> online, 'm' --> migrated */

       filemode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or  "statbits.h" under Windows/NT:

	      S_IFLNK	0xA000		symbolic link
	      S_IFREG	0x8000		regular file
	      S_IFDIR	0x4000		directory
	      S_ISUID	0004000 	set user ID on execution
	      S_ISGID	0002000 	set group ID on execution
	      S_ISVTX	0001000 	sticky bit
	      S_IRUSR	0000400 	read by owner
	      S_IWUSR	0000200 	write by owner
	      S_IXUSR	0000100 	execute/search by owner
	      S_IRGRP	0000040 	read by group
	      S_IWGRP	0000020 	write by group
	      S_IXGRP	0000010 	execute/search by group
	      S_IROTH	0000004 	read by others
	      S_IWOTH	0000002 	write by others
	      S_IXOTH	0000001 	execute/search by others

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/directory does not exist or is a null pathname.

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

       EFAULT	    path or statbuf is a NULL pointer.

       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.
