NAME

       cpg_zcb_alloc - Allocates a zero copy buffer

SYNOPSIS

       #include <corosync/cpg.h>

       int cpg_zcb_alloc(cpg_handle_t handle, size_t size, void **buffer);

DESCRIPTION

       The   cpg_zcb_alloc   function  will  allocate  a  zero  copy  buffer  for  use  with  the
       cpg_zcb_mcast_joined(3) function.  This buffer should not be used in another thread  while
       a  cpg_zcb_mcast_joined  operation is taking place on the buffer.  The buffer is allocated
       via operating system mechanisms to avoid copying in the IPC layer.

       The argument handle describes the handle on which the buffer will be allocated.

       The argument size requests a buffer of size be allocated.

       The buffer argument is set to the buffer address that is allocated by this operation.

RETURN VALUE

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

ERRORS

       The errors are undocumented.
