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:

       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;
       };

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, 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.

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).

	    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.

	      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      *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 descrip-
		    tion is greater than 255 or all file requests have errors.

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.
