int dpm_get (int nbreqfiles, struct

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;
};
This routine returns 0 if the operation was successful or -1 if
the operation failed. In the latter case, serrno is set
appropriately.
- 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.
