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 returned.

ERRORS

       The errors are undocumented.
