NAME
dpm_put - make a set of existing files available for I/O
SYNOPSIS
#include <sys/types.h>
#include "dpm_api.h"
int dpm_put (int nbreqfiles,
struct dpm_putfilereq *reqfiles,
int nbprotocols,
char **protocols,
char *u_token,
int overwrite,
time_t retrytime,
char *r_token,
int *nbreplies,
struct dpm_putfilestatus **filestatuses)
DESCRIPTION
dpm_put
makes a set of existing files available for I/O.
The input arguments are:
- nbreqfiles
-
specifies the number of files belonging to the request.
- reqfiles
-
specifies the array of file requests (dpm_putfilereq structures).
struct dpm_putfilereq {
char *to_surl;
time_t lifetime;
time_t f_lifetime;
char f_type;
char s_token[CA_MAXDPMTOKENLEN+1];
char ret_policy;
char ac_latency;
u_signed64 requested_size;
};
- nbprotocols
-
specifies the number of protocols.
- protocols
-
specifies the array of protocols.
- u_token
-
specifies the user provided description associated with the request.
- overwrite
-
if set to 1, it allows to overwrite an existing file.
- retrytime
-
This field is currently ignored.
The output arguments are:
- r_token
-
Address of a buffer to receive the system allocated token.
The buffer must be at least CA_MAXDPMTOKENLEN+1 characters long.
- nbreplies
-
will be set to the number of replies in the array of file statuses.
- filestatuses
-
will be set to the address of an array of dpm_putfilestatus structures allocated
by the API. The client application is responsible for freeing the array when not
needed anymore.
struct dpm_putfilestatus {
char *to_surl;
char *turl;
u_signed64 filesize;
int status;
char *errstring;
time_t pintime;
time_t f_lifetime;
};
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
- EFAULT
-
reqfiles,
protocols,
r_token,
nbreplies
or
filestatuses
is a NULL pointer.
- ENOMEM
-
Memory could not be allocated for marshalling the request.
- EINVAL
-
nbreqfiles
or
nbprotocols
is not strictly positive, the protocols are not supported, the length of the
user request description is greater than 255 or all file requests have errors.
- SENOSHOST
-
Host unknown.
- SEINTERNAL
-
Database error.
- SECOMERR
-
Communication error.
