DPM_COPY(3) DPM Library Functions DPM_COPY(3)

NAME

dpm_copy - copy a set of existing files

SYNOPSIS

#include <sys/types.h>
#include "dpm_api.h"

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)

DESCRIPTION

dpm_copy copies a set of existing files.

The input arguments are:

specifies the number of files belonging to the request.
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;
};
specifies the user provided description associated with the request.
if set to non zero, it allows to overwrite an existing file.
This field is currently ignored.

The output arguments are:

Address of a buffer to receive the system allocated token. The buffer must be at least CA_MAXDPMTOKENLEN+1 characters long.
will be set to the number of replies in the array of file statuses.
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;
};

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

reqfiles, r_token, nbreplies or filestatuses is a NULL pointer.
Memory could not be allocated for marshalling the request.
nbreqfiles is not strictly positive, the length of the user request description is greater than 255 or all file requests have errors.
Host unknown.
Database error.
Communication error.
