evs_leave (3)

#include <corosync/evs.h>

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

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;
  

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

The errors are undocumented.
