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

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.

NAME

       dpm_abortfiles - abort a set of file requests

SYNOPSIS

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

       int dpm_abortfiles (char *r_token, int nbsurls, char **surls, int *nbreplies, struct dpm_filestatus **filestatuses)

DESCRIPTION

       dpm_abortfiles  aborts a set of file requests.  File requests in status DPM_QUEUED are removed from the queue of pending requests, the ones
       in status DPM_READY or DPM_DONE are released (unpinned).

       The input arguments are:

       r_token
	      specifies the token returned by a previous get/put/copy request.

       nbsurls
	      specifies the number of files to be aborted.

       surls  specifies the array of file names.

       The output arguments are:

       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_filestatus structures allocated by the API. The client application is responsible  for
	      freeing the array when not needed anymore.

       struct dpm_filestatus {
	    char      *surl;
	    int       status;
	    char      *errstring;
       };

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

       ENOENT	    File does not exist.

       EACCES	    Permission denied.

       EFAULT	    r_token, surls, nbreplies or filestatuses is a NULL pointer.

       ENOMEM	    Memory could not be allocated for marshalling the request.

       EINVAL	    nbsurls is not strictly positive, the token is not known or all file requests have errors.

       ENAMETOOLONG The length of the surl exceeds CA_MAXSFNLEN.

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.
