NAME
dpm_reservespace - reserve space SYNOPSIS
#include <sys/types.h> #include "dpm_api.h" int dpm_reservespace (const char s_type, const char *u_token, const char ret_policy, const char ac_latency, u_signed64 req_t_space, u_signed64 req_g_space, time_t req_lifetime, int nbgids, gid_t *req_gids, const char *poolname, char *actual_s_type, u_signed64 *actual_t_space, u_signed64 *actual_g_space, time_t *actual_lifetime, char *s_token) DESCRIPTION
dpm_reservespace reserves space. The input arguments are: s_type specifies the type of space requested. It can be V (for Volatile), D (for Durable), P (for Permanent) or - (for any). u_token specifies the user provided description associated with the request. This argument may be NULL. ret_policy specifies the retention policy requested. It can be R (for REPLICA), O (for OUTPUT) or C (for CUSTODIAL). ac_latency specifies the access latency requested. It can be O (for ONLINE) or N (for NEARLINE). req_t_space Total space requested in bytes. req_g_space Guaranteed space requested in bytes. req_lifetime specifies the requested space lifetime (in seconds) relative to the current time. nbgids is the size of the array of group ids req_gids. req_gids when zero, the space is reserved for the user if the requester has a proxy without VOMS extension or for the group if the requester has a proxy with VOMS extension. If not zero, the space is reserved for this set of group ids. If the caller does not belong to the group, it must have ADMIN privileges. poolname If not NULL, reserves the space in that disk pool. The output arguments are: actual_s_type Type of reserved space. actual_t_space Total space reserved in bytes (best effort). actual_g_space Guaranteed space reserved in bytes. actual_lifetime Lifetime of the reserved space (in seconds) relative to the current time. s_token Address of a buffer to receive the system allocated token. 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
EACCES The caller does not belong to the group identified by req_gid and does not have ADMIN privileges. EFAULT nbgids is greater than 0 and req_gids is a NULL pointer. EINVAL The space type is invalid or the length of the user space token description is greater than 255, the space requested is not a positive value, the pool name is longer than CA_MAXPOOLNAMELEN or unknown or the number of gids is too big. SENOSHOST Host unknown. SEINTERNAL Database error. SECOMERR Communication error. LCG

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. LCG
