CPG_FD_GET(3) Corosync Cluster Engine Programmer's Manual CPG_FD_GET(3)NAMEcpg_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 identiā
fier used by the CPG library.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is
returned.
ERRORS
The errors are undocumented.
