NAME

dpm_put - make a set of existing files available for I/O

SYNOPSIS

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

int dpm_put (int nbreqfiles, struct dpm_putfilereq *reqfiles, int nbprotocols, char **protocols, char *u_token, int overwrite, time_t retrytime, char *r_token, int *nbreplies, struct dpm_putfilestatus **filestatuses)

DESCRIPTION

dpm_put 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_putfilereq structures).

struct dpm_putfilereq {
        char            *to_surl;
        time_t  lifetime;
        time_t  f_lifetime;
        char            f_type;
        char            s_token[CA_MAXDPMTOKENLEN+1];
        char            ret_policy;
        char            ac_latency;
        u_signed64      requested_size;
};

nbprotocols: specifies the number of protocols.
protocols: specifies the array of protocols.
u_token: specifies the user provided description associated with the request.
overwrite: if set to 1, 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_putfilestatus structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.

struct dpm_putfilestatus {
        char            *to_surl;
        char            *turl;
        u_signed64      filesize;
        int             status;
        char            *errstring;
        time_t  pintime;
        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, 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.
