NAME

       evs_leave - Leave one or more groups in the EVS library

SYNOPSIS

       #include <openais/evs.h>

       int    evs_leave(evs_handle_t    handle,   evs_group_t   *groups,   int
       group_entries);

DESCRIPTION

       The evs_leave function is used to leave one or more groups.  The joined
       groups  are  used with evs_mcast_joined(3) function to multicast to the
       groups joined in the argument handle.  Messages that are sent to any of
       the  joined  groups  to  the  parameter  handle  will  be  delivered by
       evs_dispatch(3).

       This call may be used more then once on a handle.

       The argument groups is used to specify the groups to leave.  A group is
       a  32 byte key.  The key is not a string, hence, the entire key is used
       when leaveing the channel.  For that reason the entire group should  be
       initialized.

       The  argument  group_entries  specifies how many entries are located in
       the groups argument.

       The groups argument is of the type evs_group_t which is defined by  the
       structure:

              typedef struct {
                      char key[32];
              } evs_groups_t;

RETURN VALUE

       This call returns the EVS_OK value if successful, otherwise an error is
       returned.

ERRORS

       The errors are undocumented.
