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.
