NAME

       lfc_getidmap - get virtual uid/gid(s) associated with a given dn/role(s)

SYNOPSIS

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

       int lfc_getidmap (const char *username, int nbgroups, const char **groupnames, uid_t *userid, gid_t *gids)

       int lfc_getidmapc (const char *username, const char *user_ca, int nbgroups, const char **groupnames, uid_t *userid, gid_t *gids)

DESCRIPTION

       lfc_getidmap gets the virtual uid/gid(s) associated with a given dn/role(s).  If the dn or any of the roles does not exist yet in the Data-
       base an entry is added to the mapping table.

       username
	      specifies the user name (dn).  It must be at most 255 characters long.

       user_ca
	      specifies the CA from the user proxy.  It must be at most 255 characters long.

       nbgroups
	      is the number of group names.

       groupnames
	      is the address of an array of group names (vo/role).  Each group name must be at most 255 characters  long.   This  pointer  can	be
	      NULL.  In this case the vo is obtained from a static mapping file.

       userid specifies the address of a buffer to receive the Virtual User Id.

       gids   specifies  the  address  of  a buffer to receive the Virtual Group Ids.  It must be big enough to receive nbgroups group ids, but at
	      least one group id in case nbgroups is zero.

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

       ENOMEM	    Memory could not be allocated in the server to receive the group names or to send back the gids.

       EACCES	    One of username, user_ca or the primary (first) group is banned.

       EFAULT	    username, userid or gids is a NULL pointer.

       EINVAL	    nbgroups is negative or the length of username, user_ca or of one of the group names exceeds 255.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       SENOMAPFND   DISABLEAUTOVIDS is set and username or one of the groups does not exist.

       ENSNACT	    Name server is not running or is being shutdown.

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.
