NAME

dpns_listrepset - list replica entries that belong to a given set

SYNOPSIS

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

struct dpns_filereplicax *dpns_listrepset (const char *setname, int flags, dpns_list *listp)

DESCRIPTION

dpns_listrepset lists replica entries that belong to a given set. This routine returns a pointer to a structure containing the current replica entry.

struct dpns_filereplicax {
        u_signed64      fileid;
        u_signed64      nbaccesses;
        time_t          ctime;          /* replica creation time */
        time_t          atime;          /* last access to replica */
        time_t          ptime;          /* replica pin time */
        time_t          ltime;          /* replica lifetime */
        char            r_type;         /* 'P' for Primary, 'S' for Secondary */
        char            status;
        char            f_type;         /* 'V' for Volatile, 'P' for Permanent */
        char            setname[37];
        char            poolname[CA_MAXPOOLNAMELEN+1];
        char            host[CA_MAXHOSTNAMELEN+1];
        char            fs[80];
        char            sfn[CA_MAXSFNLEN+1];
};

setname

is either the replica set name or the space token.

flags

may be one of the following constant:

CNS_LIST_BEGIN: the first call must have this flag set to allocate buffers and initialize pointers.
CNS_LIST_CONTINUE: all the following calls must have this flag set.
CNS_LIST_END: final call to terminate the list and free resources.

RETURN VALUE

This routine returns a pointer to a structure containing the current replica entry if the operation was successful or NULL if all entries have been returned or if the operation failed. In the latter case, serrno is set appropriately.
