DPNS_SETFSIZE(3)					      DPNS Library Functions						  DPNS_SETFSIZE(3)

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

SYNOPSIS
       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_setfsize (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize)

       int dpns_setfsizec (const char *path, struct dpns_fileid *file_uniqueid, u_signed64 filesize, const char *csumtype, char *csumvalue)

DESCRIPTION
       dpns_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 DPNS directory or the full DPNS 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.
