NAME
cpg_zcb_alloc - Allocates a zero copy buffer #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) funtion. 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 operatoin.
RETURN VALUE
This call returns the CPG_OK value if successful, otherwise an error is returned.
ERRORS
The errors are undocumented.
