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.
