CPG_FD_GET(3) Corosync Cluster Engine Programmer's Manual CPG_FD_GET(3) NAME cpg_fd_get - Dispatches callbacks from the CPG service SYNOPSIS #include <corosync/cpg.h> int cpg_fd_get(cpg_handle_t handle, int *fd); DESCRIPTION The cpg_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when cpg_dispatch(3) won't block. The handle argument may not be used directly with poll because it is not the file descriptor, but instead an internal identifier used by the CPG library. RETURN VALUE This call returns the CS_OK value if successful, otherwise an error is re- turned. ERRORS The errors are undocumented.
