 cnodes(2)                                                         cnodes(2)





 NAME
      cnodes - get a list of active nodes in cluster

 SYNOPSIS
      #include <cluster.h>

      int cnodes(cnode_t *buf);

 DESCRIPTION
      cnodes() determines the number of active cnodes in the cluster,
      including the cnode on which it is invoked.  If buf is not a null
      pointer, it must point to an array of type cnode_t with at least
      MAX_CNODE elements.  In this case, the values of the cnode IDs of the
      nodes currently in the cluster are stored in the array, terminated by
      the cnode ID 0.

 RETURN VALUE
      Upon successful completion, cnodes() returns the current number of
      active cnodes.  If the value 0 is returned, the machine is not a
      member of a cluster.  In case of an error, a value of -1 is returned
      and errno is set to indicate the error.

 ERRORS
      cnodes() may fail if:

           [EFAULT]       buf is not a null pointer and points to an illegal
                          address.  Reliable detection of this error is not
                          guaranteed.
