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.
