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,

is set appropriately.
