NAME
dpm_get - make a set of existing files available for I/O
SYNOPSIS
#include <sys/types.h>
#include "dpm_api.h"
int dpm_get (int nbreqfiles, struct dpm_getfilereq *reqfiles, int
nbprotocols, char **protocols, char *u_token, time_t retrytime, char
*r_token, int *nbreplies, struct dpm_getfilestatus **filestatuses)
DESCRIPTION
dpm_get 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_getfilereq
structures).
struct dpm_getfilereq {
char *from_surl;
time_t lifetime;
char f_type;
char s_token[CA_MAXDPMTOKENLEN+1];
char ret_policy;
int flags;
};
nbprotocols
specifies the number of protocols.
protocols
specifies the array of protocols.
u_token
specifies the user provided description associated with the
request.
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_getfilestatus
structures allocated by the API. The client application is
responsible for freeing the array when not needed anymore.
struct dpm_getfilestatus {
char *from_surl;
char *turl;
u_signed64 filesize;
int status;
char *errstring;
time_t pintime;
};
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.
