CPG_ZCB_ALLOC(3) Corosync Cluster Engine Programmer's Manual CPG_ZCB_ALLOC(3) 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.
