NAME

6       cpg_zcb_alloc - Allocates a zero copy buffer #include <corosync/cpg.h>

DESCRIPTION

11       The  cpg_zcb_alloc  function  will  allocate a zero copy buffer for use
12       with the cpg_zcb_mcast_joined(3) funtion.  This buffer  should  not  be
13       used in another thread while a cpg_zcb_mcast_joined operation is taking
14       place on the buffer.  The buffer  is  allocated  via  operating  system
15       mechanisms to avoid copying in the IPC layer.
16
17
18       The  argument  handle  describes the handle on which the buffer will be
19       allocated.
20
21       The argument size requests a buffer of size be allocated.
22
23       The buffer argument is set to the buffer address that is  allocated  by
24       this operatoin.
