int dpm_copy (int nbreqfiles, struct dpm_copyfilereq *reqfiles, char *u_token, int flags, time_t retrytime, char *r_token, int *nbreplies, struct dpm_copyfilestatus **filestatuses)

dpm_copy copies a set of existing files.

The input arguments are:

nbreqfiles

specifies the number of files belonging to the request.

reqfiles

specifies the array of file requests (dpm_copyfilereq structures).

struct dpm_copyfilereq {
	char		*from_surl;
	char		*to_surl;
	time_t	lifetime;
	char		f_type;
	char		s_token[CA_MAXDPMTOKENLEN+1];
	char		ret_policy;
	char		ac_latency;
	int		flags;
};

u_token

specifies the user provided description associated with the request.

flags

if set to non zero, 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_copyfilestatus structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.

struct dpm_copyfilestatus {
	char		*from_surl;
	char		*to_surl;
	u_signed64	filesize;
	int		status;
	char		*errstring;
	time_t	f_lifetime;
};

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

EFAULT

reqfiles, r_token, nbreplies or filestatuses is a NULL pointer.

ENOMEM

Memory could not be allocated for marshalling the request.

EINVAL

nbreqfiles is not strictly positive, 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.
