8 int cpg_zcb_alloc(cpg_handle_t handle, size_t size, void **buffer);
9
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.

28 This call returns the CPG_OK value if successful, otherwise an error is
29 returned.

32 The errors are undocumented.
