NAME

7

SYNOPSIS

9       #include <corosync/cpg.h>
10
11       int cpg_fd_get(cpg_handle_t handle, int *fd);
12

DESCRIPTION

14       The  cpg_fd_get  function  is used to retrieve the file descriptor that
15       may be used with the poll system call to determine when cpg_dispatch(3)
16       won't  block.   The  handle argument may not be used directly with poll
17       because it is not the file descriptor, but instead an internal  identi‐
18       fier used by the CPG library.
19

RETURN VALUE

21       This  call returns the CS_OK value if successful, otherwise an error is
22       returned.
23

ERRORS

25       The errors are undocumented.
