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.
