dpm_getpools - get list of pools
SYNOPSIS
#include <sys/types.h>
#include "dpm_api.h"
int dpm_getpools (int *nbpools, struct dpm_pool **dpm_pools)
DESCRIPTION
dpm_getpools gets list of pools.
The output arguments are:
nbpools
will be set to the number of replies in the array of pools.
dpm_pools
will be set to the address of an array of dpm_pool structures allocated by the API. The client application is responsible for free-
ing the array when not needed anymore. This is also necessary for the gids entry of each dpm_pool.
struct dpm_pool {
char poolname[CA_MAXPOOLNAMELEN+1];
u_signed64 defsize;
int gc_start_thresh;
int gc_stop_thresh;
int def_lifetime;
int defpintime;
int max_lifetime;
int maxpintime;
char fss_policy[CA_MAXPOLICYLEN+1];
char gc_policy[CA_MAXPOLICYLEN+1];
char mig_policy[CA_MAXPOLICYLEN+1];
char rs_policy[CA_MAXPOLICYLEN+1];
int nbgids
gid_t *gids; /* restrict the pool to given group(s) */
char ret_policy; /* retention policy: 'R', 'O' or 'C' */
char s_type; /* space type: 'V', 'D' or 'P' */
u_signed64 capacity;
u_signed64 free;
struct dpm_fs *elemp;
int nbelem;
int next_elem; /* next pool element to be used */
};
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 nbpools or dpm_pools is a NULL pointer.
ENOMEM Memory could not be allocated for storing the reply.
SENOSHOST Host unknown.
SECOMERR Communication error.

DPM_PUT(3) DPM Library Functions DPM_PUT(3)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 descrip-
tion is greater than 255 or all file requests have errors.
SENOSHOST Host unknown.
SEINTERNAL Database error.
SECOMERR Communication error.
