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.

NAME

       lfc_creatg - create a new LFC file with the specified GUID or reset it in the name server

SYNOPSIS

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

       int lfc_creatg (const char *path,  const char *guid, mode_t mode)

DESCRIPTION

       lfc_creatg creates a new LFC file with the specified GUID or resets it in the name server.

       If the file exists, the length is truncated to 0 and the mode and owner are unchanged.

       If  the file does not exist yet, an entry is created in the name server database and the file's owner ID is set to the effective user ID of
       the requestor.  The group ID of the file is set to the effective group ID of the requestor or is taken from the	parent	directory  if  the
       latter has the S_ISGID bit set.

       The  access permission bits for the file are taken from mode, then all bits set in the requestor's file mode creation mask are cleared (see
       lfc_umask(3)).

       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 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 file does not exist and write permission  on  the  parent
		    directory is denied or the file exists and write permission on the file itself is denied.

       EFAULT	    path is a NULL pointer.

       EEXIST	    File exists already with a different GUID or has replicas.

       ENOTDIR	    A component of path prefix is not a directory.

       EISDIR	    path is an existing directory.

       EINVAL	    The fileclass in the parent directory is zero or the length of the guid exceeds CA_MAXGUIDLEN.

       ENOSPC	    The name server database is full.

       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.
